fkie_cve-2026-72200

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

ntfs: detect mapping-pairs LCN accumulator overflow

The NTFS mapping-pairs parser accumulates relative LCN deltas in a signed integer. A corrupted attribute can drive that addition past the representable range.

One corrupt runlist shape sets the accumulated LCN to S64_MAX and then adds a delta of 1 in the next mapping-pairs entry.

Signed overflow is undefined and can turn an invalid runlist into a different set of physical clusters.

Check the LCN addition for overflow before storing the next run.

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…
