fkie_cve-2026-89631

In the Linux kernel, the following vulnerability has been resolved:

smb: client: reject a tree connect response whose byte count is too small

CIFSTCon() bounds its strnlen() over the byte area with the server's ByteCount minus two, which for ByteCount 0 or 1 goes negative as an int and converts to a huge size_t. The later subtraction wraps the __u16 bytes_left, and that is what bounds cifs_strndup_from_utf16(): a bound of up to 65535 against a ~16 KB cifs_req_poolp object runs off the end of the slab object, and the bytes reach userspace through tcon->nativeFileSystem in /proc/fs/cifs/DebugData.

Reject a byte area too small for what the parser consumes. Two bytes is the least it can consume, and no conformant response carries fewer. The new trace point is the 129th smb_eio_trace entry, which __mode(byte) cannot represent, so the attribute goes with it.

OESA-2026-4039 — kernel security update

Affected: openEuler:22.03-LTS-SP4: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

In the Linux kernel, the following vulnerability has been resolved:ALSA: caiaq: Use snd_card_free_when_closed() at disconnectionThe USB disconnect callback is supposed to be short and not too-longwaiting. OTOH, the current code uses snd_card_free() atdisconnection, but this waits for the close of all used fds, hence itcan take long. It eventually blocks the upper layer USB ioctls, whichmay trigger a soft lockup.An easy workaround is to replace snd_card_free() withsnd_card_free_when_closed(). This variant returns immediately whilethe release of resources is done asynchronously by the card devicerelease at the last close.This patch also splits the code to the disconnect and the free phases;the former is called immediately at the USB disconnect callback whilethe latter is called from the card destructor.(CVE-2024-56531)

In the Linux kernel, the following vulnerability has been resolved:xsk: fix OOB map writes when deleting elementsJordy says: In the xsk_map_delete_elem function an unsigned integer(map->max_entries) is compared with a user-controlled signed integer(k). Due to implicit type conversion, a large unsigned value formap->max_entries can bypass the intended bounds check: if (k >= map->max_entries) return -EINVAL;This allows k to hold a negative value (between -2147483648 and -2),which is then used as an array index in m->xsk_map[k], which resultsin an out-of-bounds access. spi…
