| In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: validate index entry key bounds [BUG] A malformed NTFS directory index entry can advertise a key_size larger than the bytes actually present in its NTFS_DE payload. Directory lookup then passes that malformed key to cmp_fnames(), which can read past the end of the kmalloc'ed index buffer.

[CAUSE] The index-header validators only validated INDEX_HDR-level geometry. They did not walk each NTFS_DE to verify entry alignment, subnode layout, or that key_size fit inside the entry payload. They also allowed a last sentinel entry to carry a non-zero key_size. [FIX] Walk every NTFS_DE in ntfs3's index-header validators and reject entries with invalid layout, mismatched subnode state, oversized key_size, or non-zero sentinel keys before lookup or log replay can consume them. | ||||
| CVE-2026-97415 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: btrfs: tree-checker: validate names in ROOT_REF and ROOT_BACKREF ROOT_REF and ROOT_BACKREF items contain a struct btrfs_root_ref followed by the subvolume name. Several readers assume that this layout is already valid and then use the on-disk name length directly. A corrupted item can therefore make those readers address bytes outside the item, and BTRFS_IOC_GET_SUBVOL_INFO can copy too many bytes into its fixed-size UAPI name buffer. Validate ROOT_REF and ROOT_BACKREF items in tree-checker before any reader uses them. Reject records that do not contain a non-empty name, whose name_len does not exactly describe the remaining item payload, or whose name exceeds BTRFS_NAME_LEN. For BTRFS_IOC_GET_SUBVOL_INFO, copy only the validated on-disk name_len instead of deriving the copy length from the item size. The ioctl result is zeroed when allocated. That leaves the existing trailing zero byte untouched. | ||||
| CVE-2026-93783 | 1 Linux | 1 Linux Kernel | 2026-10-03 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: validate skb length in rfcomm_recv_frame rfcomm_recv_frame() casts skb->data to struct rfcomm_hdr and dereferences hdr->addr and hdr->ctrl without validating skb->len first. A truncated frame with skb->len less than the minimum header size causes an out-of-bounds read of uninitialized memory. Additionally, a zero-length frame causes skb->len-- to underflow to UINT_MAX, making skb_tail_pointer() read far past the buffer. Commit 23882b828c3c ("Bluetooth: RFCOMM: validate skb length in MCC handlers") fixed the same class of missing-length-check bugs in the MCC sub-handlers, but the top-level rfcomm_recv_frame() was left unfixed. KMSAN reports: BUG: KMSAN: uninit-value in rfcomm_run ... Uninit was created at: __alloc_skb+0x474/0xb60 vhci_write+0xe9/0x870 Fix this by rejecting frames smaller than sizeof(struct rfcomm_hdr) + 1 (the minimum frame must have a 3-byte header and a 1-byte FCS). | ||||
| CVE-2026-93199 | 1 Linux | 1 Linux Kernel | 2026-10-03 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: i3c: master: Do not treat master device as a duplicate target i3c_master_search_i3c_dev_duplicate() searches the bus for another I3C device with the same PID as the reference device. The search can match master->this, causing the controller itself to be returned as a duplicate. Since the controller is not a target device, it cannot be a duplicate of one. Exclude master->this from matching so that the function only returns real duplicate target devices. | ||||
| CVE-2026-89971 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: nvme: skip the zoned limits update if the zone info query failed nvme_query_zone_info() returns either a negative errno or a positive NVMe status code, but nvme_update_ns_info_block() only tests for the negative case: ret = nvme_query_zone_info(ns, lbaf, &zi); if (ret < 0) goto out; If the device fails the Identify Namespace (I/O Command Set specific) command, or the Identify Controller command issued by nvme_set_max_append(), the positive status falls through and setup continues with the zero-initialized zone info. nvme_update_zone_info() then marks the queue zoned with chunk_sectors and ns->head->zsze set to zero. blk_validate_zoned_limits() does not check chunk_sectors, so the limits commit succeeds. blk_revalidate_disk_zones() does reject the zero zone size, but by then the limits are live and nothing rolls them back, so I/O keeps being submitted to a zoned queue with a zero zone size and disk_zone_no() shifts by ilog2(0): nvme0n1: Invalid non power of two zone size (0) UBSAN: shift-out-of-bounds in include/linux/blkdev.h:747:16 shift exponent -1 is negative disk_zone_no include/linux/blkdev.h:747 [inline] bio_straddles_zones include/linux/blkdev.h:1058 [inline] blk_zone_wplug_handle_write block/blk-zoned.c:1423 [inline] blk_zone_plug_bio.cold+0x25/0x1c8 block/blk-zoned.c:1605 blk_mq_submit_bio+0x18fb/0x2870 block/blk-mq.c:3196 submit_bh_wbc+0x575/0x740 fs/buffer.c:2824 __block_write_full_folio+0x728/0xdd0 fs/buffer.c:1933 Any device, firmware or NVMe-oF target that fails this one command reaches this. Skip the zoned limits update in that case, and log which of the two things happened: during a revalidation the queue keeps the zone geometry it was last validated with, and on a first scan the namespace is registered without zoned limits, so that it is still available as a handle for admin commands. Neither of the paths in nvme_query_zone_info() that return a positive status logs anything, so the failure would otherwise be silent. zi.zone_size is an exact indicator: every path that returns a positive status returns before it is assigned, and after that the only failure left is -ENODEV, which the caller already handles.

| CVE-2026-89859 | 1 Linux | 1 Linux Kernel | 2026-10-03 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Zero dport diagnostics buffer to avoid info leak qla2x00_do_dport_diagnostics() allocates the qla_dport_diag response buffer with kmalloc_obj() (non-zeroing) and, on success, copies the full sizeof(*dd) back to user space via sg_copy_from_buffer(). The inbound sg_copy_to_buffer() only fills as many bytes as the user request payload provides, and qla26xx_dport_diagnostics() zeroes only dd->buf. The options and unused[] fields are therefore copied out uninitialized, leaking kernel heap contents to user space. Allocate with kzalloc_obj(), matching qla2x00_do_dport_diagnostics_v2(). | ||||
| CVE-2026-89838 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: f2fs: limit recovery filename logging to stored length F2FS stores recovery filenames as a length plus a fixed-size i_name buffer. The buffer is not NUL-terminated, but recover_inode() and recover_dentry() print it with %s. For a 255-byte filename, recovery logging can read past i_name into the following raw inode fields. Print the name with a precision bounded by i_namelen and F2FS_NAME_LEN. | ||||
| CVE-2026-80836 | 1 Linux | 1 Linux Kernel | 2026-10-03 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: crypto: virtio - bound the akcipher result length virtio_crypto_dataq_akcipher_callback() sets the result length from the device-reported response length without bounding it to the destination buffer, which was allocated for the original request length. sg_copy_from_buffer() then reads that many bytes from the destination buffer; a backend reporting a larger length over-reads adjacent kernel heap into the caller's scatterlist (an out-of-bounds read). Clamp the reported length to the originally requested destination length. A conforming device reports no more than that, so valid results are unaffected. | ||||
| CVE-2026-74521 | 1 Linux | 1 Linux Kernel | 2026-10-03 | 9.1 Critical |
| In the Linux kernel, the following vulnerability has been resolved: ksmbd: use memcmp() to compare ClientGUIDs ClientGUID is a fixed-size binary value and can contain embedded NUL bytes. strncmp() stops comparing at the first NUL byte, so different ClientGUID values can incorrectly be treated as equal. Use memcmp() in SMB3 multichannel session binding and FSCTL_VALIDATE_NEGOTIATE_INFO to compare all SMB2_CLIENT_GUID_SIZE bytes. | ||||

| CVE-2026-77987 | 1 Github | 1 Enterprise Server | 2026-10-02 | 9.8 Critical |
| A server-side request forgery (SSRF) vulnerability was identified in the notebook viewer of GitHub Enterprise Server. The notebook viewer validated the scheme and host of a user-supplied URL but did not validate the port, allowing requests to be directed to internal services listening on other ports of the same appliance. Response bodies were not returned to the requester, but response timing acted as an oracle that allowed instance secrets to be extracted character by character. An extracted secret could then be used in a separate interaction with an internal service to obtain remote code execution on the appliance. Exploitation required network access to the instance and was unauthenticated when private mode was disabled, or required any authenticated user when private mode was enabled. This vulnerability affected GitHub Enterprise Server versions 3.17 through 3.22 and was fixed in versions 3.22.1, 3.21.6, 3.20.8, 3.19.12, 3.18.15, and 3.17.21. This vulnerability was reported through the GitHub Bug Bounty program. | ||||
