| CVE-2026-90403 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: rtlwifi: pci: fix error path in rtl_pci_probe() In the last error path in rtl_pci_probe(), the cleanup functions are skipped due to a wrong goto label. Moreover, the successful call to rtl_init_rfkill(), ieee80211_register_hw(), rtl_debug_add_one() have to be reverted. Fix this issue by updating the labels and adding the relevant cleanup functions to the last error path. | ||||
| CVE-2026-93039 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.4 High |
| In the Linux kernel, the following vulnerability has been resolved: ASoC: meson: Keep link pointers valid on realloc failure meson_card_reallocate_links() grows the DAI link and private data arrays with two consecutive krealloc() calls and updates the owner pointers only after both calls have succeeded. A successful krealloc() may move the data: it frees the old block and returns a new one. When that happens for the link array and the second krealloc() then fails, card->dai_link still points to the block that krealloc() already freed, and the error path frees the new block too. The probe error path then calls meson_card_clean_references(), which dereferences card->dai_link and kfree()s it again, resulting in a use-after-free and a double free. Commit card->dai_link and card->num_links right after the first krealloc() succeeds, so the pointer always refers to a valid allocation that meson_card_clean_references() can walk and free. krealloc() with __GFP_ZERO zero-initializes the added entries, so walking them on the error path is safe. With both failure paths reduced to a plain return, drop the goto labels and the error message. | ||||
| CVE-2026-93042 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma: Terminate all descriptors without callbacks The DMA Engine client documentation says in the "Terminate APIs" section of Documentation/driver-api/dmaengine/client.rst: "No callback functions will be called for any incomplete transfers." dw-edma instead calls vchan_cookie_complete() when a deferred STOP reaches the interrupt handler. This schedules a callback for the active descriptor and leaves other issued or submitted descriptors queued. A late callback after dmaengine_terminate_sync() can dereference client state that has already been freed, while leftover descriptors may later restart into reused buffers or leak. Move all issued and submitted descriptors to the terminated list whenever termination completes. For a pending STOP, do this from both the DONE and ABORT paths. Complete their cookies in order without scheduling callbacks. A STOP can remain pending until the running transfer raises an interrupt. Make device_synchronize() wait for such a pending STOP to complete before releasing terminated descriptors. Reuse it from free_chan_resources(), then release the remaining virt-dma resources. Sleep instead of busy-polling while waiting, and warn if the existing timeout expires. | ||||
| CVE-2026-93070 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: media: ipu6: Do not free aux device pdata after init ipu6_bus_initialize_device() stores the isys/psys pdata pointer in struct ipu6_bus_device and initializes the auxiliary device. After that point, error unwinding must drop the auxiliary device reference and let ipu6_bus_release() free both the bus device and adev->pdata. The isys and psys init paths already call put_device() when MMU initialization fails, and ipu6_bus_add_device() calls auxiliary_device_uninit() on auxiliary_device_add() failure. Both paths therefore run the bus release callback. The extra kfree(pdata) in the callers can release the same object a second time. Remove the manual pdata frees after the auxiliary device has been initialized. This issue was found by a static analysis checker and confirmed by manual source review. | ||||
| CVE-2026-92507 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Fix potential use after free in ib_dealloc_pd_user() When accessing a PD via the netlink path the only synchronization mechanism for the said PD is rdma_restrack_get(). Currently, rdma_restrack_del() is invoked at the end of ib_dealloc_pd_user(), which is too late, since by that point vendor-specific resources associated with the PD might already be freed. This can leave a short window where the PD remains accessible through restrack, leading to a potential use-after-free. Fix this by moving the rdma_restrack_begin_del() call to the start of ib_dealloc_pd_user(), ensuring that the PD is removed from restrack before its internal resources are released. This guarantees that no new users hold references to a PD that is in the process of destruction. In addition, this change preserves the intended inverted order between create and destroy routines: resources are added to restrack at the end of successful creation, and hence shall be removed from the restrack first thing during the destruction flow, which keeps the lifecycle management consistent and predictable. | ||||
| CVE-2026-92508 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Fix potential use after free in ib_free_cq() When accessing a CQ via the netlink path the only synchronization mechanism for the said CQ is rdma_restrack_get(). Currently, rdma_restrack_del() is invoked at the end of ib_free_cq(), which is too late, since by that point vendor-specific resources associated with the CQ might already be freed. This can leave a short window where the CQ remains accessible through restrack, leading to a potential use-after-free. Fix this by moving the rdma_restrack_del() call to be before the freeing of the vendor-specific resources ensuring that the CQ is removed from restrack before its internal resources are released. This guarantees that no new users hold references to a CQ that is in the process of destruction. | ||||

| In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Fix potential use after free in ib_destroy_srq_user() When accessing a SRQ via the netlink path the only synchronization mechanism for the said SRQ is rdma_restrack_get(). Currently, rdma_restrack_del() is invoked at the end of ib_destroy_srq_user(), which is too late, since by that point vendor-specific resources associated with the SRQ might already be freed. This can leave a short window where the SRQ remains accessible through restrack, leading to a potential use-after-free. Fix this by moving the rdma_restrack_begin_del() call to the start of ib_destroy_srq_user(), ensuring that the SRQ is removed from restrack before its internal resources are released. This guarantees that no new users hold references to a SRQ that is in the process of destruction. In addition, this change preserves the intended inverted order between create and destroy routines: resources are added to restrack at the end of successful creation, and hence shall be removed from the restrack first thing during the destruction flow, which keeps the lifecycle management consistent and predictable. | ||||
| CVE-2026-92518 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: riscv, bpf: Fix kernel stack corruption in tailcall with CFI When CONFIG_CFI_CLANG is enabled, prog->bpf_func already skips the kcfi instruction during setup. Including it again in the tailcall jump offset causes it to jump over an extra 4 bytes, skipping the stack pointer adjustment, which will result in kernel stack corruption. | ||||
| CVE-2026-92525 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Validate num_sge/cur_sge before indexing wqe->dma.sge[] For a user QP, qp->sq.queue is a ring the application writes directly, so rxe_post_send() takes the is_user branch and only schedules send_task without validating the WQE. rxe_requester() consumes it in place via req_next_wqe() and calls copy_data(), which indexes &wqe->dma.sge[cur_sge] with the attacker-controlled num_sge/cur_sge. Only the kernel path bounds num_sge (validate_send_wr()); the user WQE is never checked, so a local unprivileged user can post a WQE with an out-of-range cur_sge or oversized num_sge and force an out-of-bounds read of the per-WQE sge array in copy_data() (vmalloc OOB read, local DoS). Bound num_sge to qp->sq.max_sge in rxe_requester() before use, the way get_srq_wqe() already guards SRQ entries, and bound cur_sge only when the WQE carries payload (dma.resid): copy_data() returns early on a zero-length copy before touching dma->sge[], so a zero-payload WQE -- the only kind a max_sge == 0 QP can post -- stays valid. Reproduced under KASAN; the vmalloc-out-of-bounds in copy_data() is gone. | ||||
| CVE-2026-93063 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mei: check SAP message length before reading it Verify the SAP message size is not larger than the local buffer before reading the message to avoid buffer overflow. | ||||
| CVE-2026-93074 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: dax/fsdev: use __va(phys) for kaddr in direct_access Use __va(phys) instead of virt_addr + linear_offset for the kaddr return in __fsdev_dax_direct_access(). The previous code added a device-linear byte offset to virt_addr (which is __va of ranges[0]), but for multi-range devices with physical gaps between ranges, this linear arithmetic crosses the gap and produces a wrong kernel virtual address. Using __va(phys) where phys comes from dax_pgoff_to_phys() is correct for any range layout because the direct map translates each physical address independently. This leaves dev_dax->virt_addr write-only, so remove the field (suggested by Dave Jiang). | ||||
| CVE-2026-93079 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: cxl/features: Reject Get Feature count larger than the output buffer cxlctl_get_feature() sizes its output buffer from the user's fwctl_rpc.out_len, but the device is told to write cxl_mbox_get_feat_in.count bytes into rpc_out->payload, which is a separate user-controlled value. Nothing bounds count against out_len, so a small out_len with a large count overflows the kvzalloc()'d buffer. A heap OOB write reachable from FWCTL_RPC. Reject requests where count exceeds the available payload room, before allocating. | ||||
| CVE-2026-93112 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Require a BPF cpumask for bpf_cpumask_populate() bpf_cpumask_populate() writes to its destination with bitmap_copy(), but the destination is typed as struct cpumask *. That allows the verifier to accept borrowed cpumask pointers returned by read-only kfuncs, such as scx_bpf_get_online_cpumask(), as a writable destination. Make the destination a struct bpf_cpumask * so populate follows the same ownership rule as the other mutating cpumask kfuncs. Query kfuncs continue to accept const struct cpumask * inputs. | ||||
| CVE-2026-93192 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Clear queue->active_job when v3d_fence_create() fails The run_job() callbacks for BIN, RENDER, TFU and CSD assign the incoming job to queue->active_job before calling v3d_fence_create(). If v3d_fence_create() fails, the callback returns NULL without clearing active_job, leaving a dangling pointer. Create a failure path in all run_job() callbacks that clears the active job before returning NULL. The BIN path takes queue->queue_lock around the clear as it races against v3d_overflow_mem_work(); RENDER, TFU and CSD paths have no concurrent reader, so the clear is lock-free. | ||||
| CVE-2026-93130 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: platform/x86: dell-wmi-base: Fix resource leak on module load failure We need to properly clean up the SMBIOS request and the privacy driver when the module load fails. | ||||
| CVE-2026-93127 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Drop scalar id on sign-extending narrowing stack fills When a spilled scalar is filled back with a sign-extending narrowing load (BPF_MEMSX), check_stack_read_fixed_off() copies the spilled register including its scalar id, but coerce_reg_to_size_sx() then sign-extends the filled register's value. If the same slot is also filled with a plain zero-extending load (BPF_MEM), both destination registers share the id yet hold different values. A later 'if <zext-reg> == const' then refines the sign-extended register through sync_linked_regs() to a value it does not have at runtime (e.g. the verifier believes 0x80000000 while the register is 0xffffffff80000000), which can be turned into an out-of-bounds access. Drop the shared scalar id at the sign-extension site in check_mem_access() when sign extension actually changes the value, mirroring the BPF_MOVSX handling in check_alu_op() (no_sext = reg_umax < 2^(size*8-1)). | ||||
| CVE-2026-93151 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: nvmet-rdma: fix response resource leak on queue teardown When an nvme target with rdma transport is removed while I/Os are in flight, a response can be posted but its send completion is never delivered before the connection is torn down. As a result nvmet_rdma_send_done() and nvmet_rdma_release_rsp() are never called for the response, and this leaks the allocated RDMA read/write context and request SGLs. These leaks are recreated by running blktests nvme/061 with the rdma transport and the siw driver. Kernel kmemleak feature reports them as follows: unreferenced object 0xffff88812bc490c0 (size 32): comm "kworker/2:1H", pid 409, jiffies 4307744490 backtrace (crc 89afd339): __kmalloc_noprof+0x5f9/0x890 sgl_alloc_order+0x7b/0x380 nvmet_req_alloc_sgls+0x290/0x4f0 [nvmet] nvmet_rdma_map_sgl_keyed+0x241/0x12e0 [nvmet_rdma] nvmet_rdma_handle_command+0x73e/0xb80 [nvmet_rdma] __ib_process_cq+0x149/0x4c0 [ib_core] ib_cq_poll_work+0x49/0x160 [ib_core] process_one_work+0x8b2/0x1640 worker_thread+0x5fd/0xfe0 kthread+0x367/0x460 ret_from_fork+0x655/0x9d0 ret_from_fork_asm+0x1a/0x30 unreferenced object 0xffff88814bd05e80 (size 64): comm "kworker/3:1H", pid 148, jiffies 4295195428 backtrace (crc e35510cb): __kmalloc_noprof+0x5f9/0x890 rdma_rw_ctx_init+0x333/0x1fa0 [ib_core] nvmet_rdma_map_sgl_keyed+0x5c8/0x12e0 [nvmet_rdma] nvmet_rdma_handle_command+0x73e/0xb80 [nvmet_rdma] __ib_process_cq+0x149/0x4c0 [ib_core] ib_cq_poll_work+0x49/0x160 [ib_core] process_one_work+0x8b2/0x1640 worker_thread+0x5fd/0xfe0 kthread+0x367/0x460 ret_from_fork+0x655/0x9d0 ret_from_fork_asm+0x1a/0x30 To avoid the memory leaks, reclaim the memory of the in-flight responses when the queue QP is torn down.

| CVE-2026-93203 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: batman-adv: bla: avoid CRC corruption due to parallel claim add batadv_bla_add_claim() is used to add claims and modify the backbone of claims for CLAIM frames from remote backbones and local packets. When it handles a claim, it needs to either * add the new claim's CRC to the backbone CRC * remove the already existing claim's CRC from the old backbone and add it to the new backbone But when the "new" claim code was running in parallel to the "change backbone" code, it can happen that the CRC was invalid because the backbone_gw of the claim was changed twice in the "new" claim code path: * CPU0 creates the claim for gateway A and publishes it in the claim hash. The crc16 of the address has not yet been added to A's crc at this point. * CPU1 processes a claim frame of gateway B for the same client, finds the just published claim, and performs the ownership change: it switches the pointer to B, removes the crc16 from A's crc - which never contained it - and adds it to B's crc. * CPU0 continues behind the creation branch, unconditionally switches the pointer back to A without compensating B's crc (its remove_crc is false for the creation path), and finally adds the crc16 to A's crc The CRC is then wrong for both: * claim belongs to A: but CRC is not part of backbone A's CRC * claim doesn't belong to B: CRC is still part of backbone B's CRC This wrong CRC is never recomputated from the stored claims. For local backbone claims, this can also not recovered using syncs. To avoid this, split the functionality in clear separate parts: * new claim which always adds claim CRC to the backbone CRC (but never changes the already set backbone_gw of the claim back) * update of existing claim which automatically changes the backbone_gw entry and only updates both backbone CRCs when there was an actual change | ||||
| CVE-2026-93159 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: crypto: atmel-sha204a - fix heap info leak on I2C transfer failure The nonblocking RNG path allocates a work_data structure to track the state of an in-flight asynchronous I2C request. This pointer is stored in rng->priv and later consumed by the read path once the transaction completes. If the underlying I2C transfer fails, the completion callback is invoked with a non-zero status. In this case, the allocated work_data is not usable for producing RNG output and must not remain associated with the hwrng state. Previously, the failure path only logged a warning but left the pointer state uncleared, which can result in subsequent read attempts observing stale state and interpreting it as valid completion data. Fix this by freeing the pending work_data. The I2C transaction reports an error. This ensures that failed requests do not leave residual state behind that could be interpreted as valid RNG data on later reads. Clearing rng->priv is done at the subsequent call to nonblocking read. | ||||

| In the Linux kernel, the following vulnerability has been resolved: cpufreq: imx6q: fix out-of-bounds write when probed more than once imx6_soc_volt is allocated fresh on every probe, sized to the number of ARM OPPs: imx6_soc_volt = devm_kcalloc(cpu_dev, num, sizeof(*imx6_soc_volt), GFP_KERNEL); but it is filled through soc_opp_count, which has static storage and is never reset. A second bind after an unbind keeps indexing from where the first one stopped, and writes past the end of the new array. Unbinding and rebinding the driver on qemu's mcimx6ul-evk, under KASAN: BUG: KASAN: slab-out-of-bounds in imx6q_cpufreq_probe+0x3b0/0xa34 Write of size 4 at addr c5e90480 by task binder/73 imx6q_cpufreq_probe from platform_probe+0x88/0xe4 platform_probe from really_probe+0x108/0x384 bind_store from kernfs_fop_write_iter+0x1b4/0x28c The write lands one u32 past the end of the allocation. soc_opp_count is only read a few lines below the loop that fills it, so it never needed static storage.
