| CVE-2026-74383 | 1 Linux | 1 Linux Kernel | 2026-08-22 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix out-of-bounds access in nvme_setup_descriptor_pools nvme_setup_descriptor_pools() indexes dev->descriptor_pools[] using the numa_node forwarded from hctx->numa_node by its single caller, nvme_init_hctx_common(). On a non-NUMA kernel hctx->numa_node is NUMA_NO_NODE (-1). Because the parameter was declared 'unsigned', the value becomes UINT_MAX and the index walks off the array (sized to nr_node_ids), faulting during nvme_alloc_ns() and leaving the namespace without a /dev node. Reproduces on any NVMe controller probed by a CONFIG_NUMA=n kernel: BUG: unable to handle page fault for address: ffff889101603d38 RIP: 0010:nvme_init_hctx_common+0x5a/0x190 [nvme] Call Trace: nvme_init_hctx+0x10/0x20 [nvme] nvme_alloc_ns+0x9e/0xa10 [nvme_core] nvme_scan_ns+0x301/0x3b0 [nvme_core] nvme_scan_ns_async+0x23/0x30 [nvme_core] Switch the parameter to int and fall back to node 0 when it is NUMA_NO_NODE; node 0 is always present. | ||||
| CVE-2026-74386 | 1 Linux | 1 Linux Kernel | 2026-08-22 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: fix page fragment cache leak in error path In nvmet_tcp_alloc_queue(), when a connection is closed during the allocation process (e.g., nvmet_tcp_set_queue_sock() returns -ENOTCONN), the error handling jumps to out_destroy_sq and then to out_ida_remove without draining the page fragment cache. Although nvmet_tcp_free_cmd() is called in some error paths to release individual page fragments, the underlying page cache reference held by queue->pf_cache is never released. The first allocation using pf_cache is the call to nvmet_tcp_alloc_cmd() for queue->connect, which happens after ida_alloc() returns successfully. This results in a page leak each time a connection fails during allocation, which could lead to memory exhaustion over time if connections are repeatedly opened and closed. Fix this by calling page_frag_cache_drain() before freeing the queue structure in the out_ida_remove label. | ||||
| CVE-2026-74391 | 1 Linux | 1 Linux Kernel | 2026-08-22 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: tracing: Bound synthetic-field strings with seq_buf The synthetic field helpers build a prefixed synthetic variable name and a generated hist command in fixed MAX_FILTER_STR_VAL buffers. The current code appends those strings with raw strcat(), so long key lists, field names, or saved filters can run past the end of the staging buffers. Build both strings with seq_buf and propagate -E2BIG if either the synthetic variable name or the generated command exceeds MAX_FILTER_STR_VAL. This keeps the existing tracing-side limit while using the helper intended for bounded command construction. [ sdr: Moved struct seq_buf *s for upside-down x-mas tree formatting ] | ||||
| CVE-2026-74369 | 1 Linux | 1 Linux Kernel | 2026-08-22 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: liveupdate: fix u-a-f in luo_file_unpreserve_files() and luo_file_finish() In luo_file_unpreserve_files() and luo_file_finish(), reorder module_put() and xa_erase() to ensure the file handler module remains pinned while its operations are being accessed. Specifically, luo_get_id() dereferences fh->ops->get_id, so the module reference must be held until after xa_erase() (which calls luo_get_id) completes. For luo_file_finish(), this requires moving the module_put() call out of the luo_file_finish_one() helper and into the main loop of luo_file_finish() itself. | ||||
| CVE-2026-74392 | 1 Linux | 1 Linux Kernel | 2026-08-22 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: dm: limit target bio polling to one shot dm_poll_bio() is the ->poll_bio() callback for a stacked dm device. The caller only knows about the dm queue, so it may decide to do a spinning poll if it thinks a single queue is being polled. Passing those flags unchanged to the mapped clone lets blk_mq_poll() spin on a target queue from inside dm_poll_bio(). With io_uring IOPOLL on a dm-stripe target this can keep a task in dm_poll_bio() -> bio_poll() -> blk_mq_poll() long enough to trigger an RCU CPU stall, before io_uring gets back to io_iopoll_check() and its need_resched() check. Keep dm's ->poll_bio() bounded by forcing one-shot polling for target bios. The caller can invoke dm_poll_bio() again if it wants to keep polling, and it also gets a chance to reap completions or reschedule between passes. | ||||

| In the Linux kernel, the following vulnerability has been resolved: drm/syncobj: Fix memory leak in drm_syncobj_find_fence() Commit 18226ba52159 ("drm/syncobj: reject invalid flags in drm_syncobj_find_fence") forgot to take into account the fact that drm_syncobj_find() takes a reference to syncobj and returns early without dropping the reference, leading to memory leaks.

| CVE-2026-74419 | 1 Linux | 1 Linux Kernel | 2026-08-22 | 7.3 High |
| In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Adjust size for copy_to_user() The amount of data returned to user space should be limited by the buffer size provided by the application. If the buffer is smaller than the data size, return only the portion that fits instead of failing. | ||||
| CVE-2026-74423 | 1 Linux | 1 Linux Kernel | 2026-08-22 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix leak when pinning ubuf pages When pin_user_pages_fast() returns fewer pages than requested, the pages that were successfully pinned are not released, leading to a leak. Fix this by unpinning any partially pinned pages before returning failure. | ||||

| CVE-2026-74416 | 1 Linux | 1 Linux Kernel | 2026-08-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/radeon: fix memory leak in radeon_ring_restore() on lock failure radeon_ring_restore() takes ownership of the data buffer allocated by radeon_ring_backup(). The caller (radeon_gpu_reset()) only frees it in the non-restore branch; in the restore branch it relies on radeon_ring_restore() to free it. If radeon_ring_lock() fails, the function returned early without calling kvfree(data), leaking the ring backup buffer on every GPU reset that fails at the lock stage. During repeated GPU resets this causes cumulative kernel memory exhaustion. Free data before returning the error. | ||||
| CVE-2026-74420 | 1 Linux | 1 Linux Kernel | 2026-08-21 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/gpusvm: Reject VMAs with VM_IO or VM_PFNMAP when creating SVM ranges VMAs marked with VM_IO or VM_PFNMAP are not backed by struct page objects, which GPUSVM requires in order to operate correctly. In particular, get_pages() relies on hmm_range_fault() to resolve struct pages for the target range. Attempting to create an SVM range on such VMAs results in repeated get_pages() failures and can lead to an infinite loop inside a driver’s page‑fault handler. Prevent this by rejecting ranges on VM_IO or VM_PFNMAP VMAs and returning -EIO. | ||||

| CVE-2026-74454 | 1 Linux | 1 Linux Kernel | 2026-08-21 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Supply the overflow slot size in BPOS, not the whole bin BO size vc4_overflow_mem_work() points BPOA at a 512KB slot inside the 16MB binner BO, but writes the size of the whole BO to BPOS. On every binner out-of-memory event the PTB is therefore authorized to write tile lists across all the other slots (which may hold the tile state, tile alloc and overflow memory of in-flight jobs) and, for any slot but the first, past the end of the binner BO into unrelated CMA memory. Since CMA pages are recycled into page cache and user allocations, this is arbitrary memory corruption by GPU DMA. In practice it shows up as GPU hangs with corrupted control list pointers, userspace heap corruption, a GPU that stays permanently wedged after the first hang, and occasional full system crashes, whenever a job overflows the initial binner slot. The bug dates back to the conversion from a dedicated overflow BO (where writing the full BO size was correct) to the slotted binner BO. | ||||
| CVE-2026-74507 | 1 Linux | 1 Linux Kernel | 2026-08-21 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: HIDP: validate numbered report payloads When hidp_get_raw_report() waits for a numbered report, hidp_process_data() compares the expected report number with skb->data[0]. A connected HIDP peer can reply with only a DATA transaction header, leaving the skb empty after the header is removed. KMSAN reports an uninitialized-value use in hidp_session_run(), with the value originating in __alloc_skb() through vhci_write(). The transaction header checks remove the empty-frame reports, but this report remains until the payload check is added. The comparison can also consume a peer-controlled byte beyond the declared L2CAP PDU. A DATA | FEATURE response followed by an extra 0x01 byte made the current code accept that byte as report ID 1 and complete HIDIOCGFEATURE with a zero-byte result. With this change the malformed response is rejected with -EIO, while a subsequent valid response still succeeds. Require a payload byte before comparing a numbered report ID. Unnumbered reports continue to accept an empty payload. | ||||

| CVE-2026-53509 | 1 Ondata | 1 Ckan-mcp-server | 2026-08-21 | 5.7 Medium |
| CKAN MCP Server is a tool for querying CKAN open data portals. A known vulnerability CVE-2026-33060 indicated tools including ckan_package_search and sparql_query that accept a base_url parameter had the risk of making HTTP requests to arbitrary endpoints without restriction. A fix was applied to filter out ip addresses. However, a method to bypass exists prior to version 0.4.106. CKAN MCP Server validates caller-supplied CKAN server URLs by inspecting only the parsed hostname string before issuing outbound HTTP requests. In `src/utils/http.ts`, hostname aliases such as `ip6-localhost` are not equal to `localhost`, are not dotted IPv4 literals, and are not bracketed IPv6 literals, so they pass the SSRF filter but can resolve to loopback when the server performs the request. A remote MCP caller that can invoke CKAN tools with a `server_url` can therefore make the server connect to local or private addresses and, for CKAN-shaped responses, receive response-derived data. The updated fix in version 0.4.106 replaced the single `hostname === 'localhost'` check with a blocked-hostname `Set` covering `ip6-localhost` and `ip6-loopback`. | ||||
