https://notcve.org/view.php?id=CVE-2022-42703
mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse. El archivo mm/rmap.c en el kernel de Linux versiones anteriores a 5.19.7, presenta un uso de memoria previamente liberada relacionado con un doble reúso de la hoja anon_vma A memory leak flaw with use-after-free capability was found in the Linux kernel. The VMA mm/rmap.c functionality in the is_mergeable_anon_vma() function continuously forks, using memory operations to trigger an incorrect reuse of leaf anon_vma. This issue allows a local attacker to crash the system. • https://bugs.chromium.org/p/project-zero/issues/detail?id=2351 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.19.7 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2555283eb40df89945557273121e9393ef9b542b https://github.com/torvalds/linux/commit/2555283eb40df89945557273121e9393ef9b542b https://googleprojectzero.blogspot.com/2022/12/exploiting-CVE-2022-42703-bringing-back-the-stack-attack.html https://access.redhat.com/security/cve/CVE-2022-42703 https://bugzilla.redhat&# • CWE-416: Use After Free •

A race condition flaw was found in the Linux kernel sound subsystem due to improper locking. It could lead to a NULL pointer dereference while handling the SNDCTL_DSP_SYNC ioctl. A privileged local user (root or member of the audio group) could use this flaw to crash the system, resulting in a denial of service condition Se ha encontrado un fallo de condición de carrera en el subsistema de sonido del kernel de Linux debido a un bloqueo inapropiado. Podría conllevar a una desreferencia de puntero NULL mientras es manejado el ioctl SNDCTL_DSP_SYNC.
