https://notcve.org/view.php?id=CVE-2022-0995
An out-of-bounds (OOB) memory write flaw was found in the Linux kernel’s watch_queue event notification subsystem. This flaw can overwrite parts of the kernel state, potentially allowing a local user to gain privileged access or cause a denial of service on the system. Se encontró un fallo de escritura en memoria fuera de límites (OOB) en el subsistema de notificación de eventos watch_queue del kernel de Linux. este fallo puede sobrescribir partes del estado del kernel, permitiendo potencialmente a un usuario local conseguir acceso privilegiado o causar una denegación de servicio en el sistema The Linux watch_queue filter suffers from an out of bounds write vulnerability. • https://github.com/Bonfee/CVE-2022-0995 https://github.com/1nzag/CVE-2022-0995 https://github.com/AndreevSemen/CVE-2022-0995 http://packetstormsecurity.com/files/166770/Linux-watch_queue-Filter-Out-Of-Bounds-Write.html http://packetstormsecurity.com/files/166815/Watch-Queue-Out-Of-Bounds-Write.html https://bugzilla.redhat.com/show_bug.cgi?id=2063786 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=93ce93587d36493f2f86921fa79921b3cba63fbb https://security.netapp.com • CWE-787: Out-of-bounds Write •
