https://notcve.org/view.php?id=CVE-2022-1353
A vulnerability was found in the pfkey_register function in net/key/af_key.c in the Linux kernel. This flaw allows a local, unprivileged user to gain access to kernel memory, leading to a system crash or a leak of internal kernel information. Se encontró una vulnerabilidad en la función pfkey_register en el archivo net/key/af_key.c en el kernel de Linux. Este fallo permite a un usuario local no privilegiado acceder a la memoria del kernel, conllevando a un bloqueo del sistema o un filtrado de información interna del kernel • https://bugzilla.redhat.com/show_bug.cgi?id=2066819 https://github.com/torvalds/linux/commit/9a564bccb78a76740ea9d75a259942df8143d02c https://lists.debian.org/debian-lts-announce/2022/07/msg00000.html https://security.netapp.com/advisory/ntap-20220629-0001 https://www.debian.org/security/2022/dsa-5127 https://www.debian.org/security/2022/dsa-5173 https://access.redhat.com/security/cve/CVE-2022-1353 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer •

https://notcve.org/view.php?id=CVE-2022-29582
In the Linux kernel before 5.17.3, fs/io_uring.c has a use-after-free due to a race condition in io_uring timeouts. This can be triggered by a local user who has no access to any user namespace; however, the race condition perhaps can only be exploited infrequently. En el kernel de Linux versiones anteriores a 5.17.3, el archivo fs/io_uring.c presenta un uso de memoria previamente liberada debido a una condición de carrera en la función io_uring timeouts. Esto puede ser desencadenado por un usuario local que no tenga acceso a ningún espacio de nombres de usuario; sin embargo, la condición de carrera quizás sólo pueda ser explotada con poca frecuencia • https://github.com/Ruia-ruia/CVE-2022-29582-Exploit http://www.openwall.com/lists/oss-security/2022/04/22/4 http://www.openwall.com/lists/oss-security/2022/08/08/3 http://www.openwall.com/lists/oss-security/2024/04/24/3 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.17.3 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e677edbcabee849bfdd43f1602bccbecf736a646 https://github.com/torvalds/linux/commit/e677edbcabee849bfdd43f1602bccbecf736a646 https • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

https://notcve.org/view.php?id=CVE-2022-1048
A use-after-free flaw was found in the Linux kernel’s sound subsystem in the way a user triggers concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the system.
