CVE-2022-29582
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') •
CVE-2022-1048 – kernel: race condition in snd_pcm_hw_free leading to use-after-free
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. Se ha encontrado un fallo de uso de memoria previamente liberada en el subsistema de sonido del kernel de Linux en la forma en que un usuario desencadena las llamadas concurrentes de PCM hw_params. La ioctls hw_free o una condición de carrera similar ocurre dentro de ALSA PCM para otras ioctls. • https://bugzilla.redhat.com/show_bug.cgi?id=2066706 https://lore.kernel.org/lkml/20220322170720.3529-5-tiwai%40suse.de/T/#m1d3b791b815556012c6be92f1c4a7086b854f7f3 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-2022-1048 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVE-2022-1016 – kernel: uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM
https://notcve.org/view.php?id=CVE-2022-1016
A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. Se ha encontrado un fallo en el kernel de Linux en el archivo net/netfilter/nf_tables_core.c:nft_do_chain, que puede causar un uso de memoria previamente liberada. Este problema necesita manejar "return" con las precondiciones apropiadas, ya que puede conllevar a un problema de filtrado de información del kernel causado por un atacante local no privilegiado • http://blog.dbouman.nl/2022/04/02/How-The-Tables-Have-Turned-CVE-2022-1015-1016 https://access.redhat.com/security/cve/CVE-2022-1016 https://bugzilla.redhat.com/show_bug.cgi?id=2066614 https://seclists.org/oss-sec/2022/q1/205 • CWE-824: Access of Uninitialized Pointer CWE-909: Missing Initialization of Resource •
