https://notcve.org/view.php?id=CVE-2022-42722
In the Linux kernel 5.8 through 5.19.x before 5.19.16, local attackers able to inject WLAN frames into the mac80211 stack could cause a NULL pointer dereference denial-of-service attack against the beacon protection of P2P devices. En el kernel de Linux versiones 5.8 hasta 5.19.14, los atacantes locales capaces de inyectar tramas WLAN en la pila mac80211 podían causar un ataque de denegación de servicio por desreferencia de puntero NULL contra la protección de balizas de los dispositivos P2P A flaw was found in P2P-Device in wifi in ieee80211_rx_h_decrypt in net/mac80211/rx.c in the Linux kernel, leading to a denial of service. • http://packetstormsecurity.com/files/169951/Kernel-Live-Patch-Security-Notice-LSN-0090-1.html http://www.openwall.com/lists/oss-security/2022/10/13/5 https://bugzilla.suse.com/show_bug.cgi?id=1204125 https://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless.git/commit/?id=b2d03cabe2b2e150ff5a381731ea0355459be09f https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GGHENNMLCWIQV2LLA56BJNFIUZ7WB4IY&# • CWE-476: NULL Pointer Dereference CWE-705: Incorrect Control Flow Scoping •
CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 2CVE-2022-42703 – kernel: use-after-free related to leaf anon_vma double reuse
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 •
