https://notcve.org/view.php?id=CVE-2022-41222
mm/mremap.c in the Linux kernel before 5.13.3 has a use-after-free via a stale TLB because an rmap lock is not held during a PUD move. El archivo mm/mremap.c en el kernel de Linux versiones anteriores a 5.13.3, presenta un uso de memoria previamente liberada por medio de un TLB obsoleto porque un bloqueo rmap no es mantenido durante un movimiento PUD A use-after-free flaw was found in the Linux kernel’s mm/mremap memory address space accounting source code in how a race condition happens between rmap walk and mremap. This flaw allows a local user to crash or potentially escalate their privileges on the system. Linux stable versions 5.4 and 5.10 suffers from a page use-after-free via stale TLB caused by an rmap lock not held during PUD move. • http://packetstormsecurity.com/files/168466/Linux-Stable-5.4-5.10-Use-After-Free-Race-Condition.html http://packetstormsecurity.com/files/171005/Kernel-Live-Patch-Security-Notice-LNS-0091-1.html https://bugs.chromium.org/p/project-zero/issues/detail?id=2347 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.13.3 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=97113eb39fa7972722ff490b947d8af023e1f6a2 https://lists.debian.org/debian-lts-announce/2022/11/msg00001 • CWE-416: Use After Free •

CVSS: 7.8EPSS: 0%CPEs: 3EXPL: 0CVE-2022-2585 – kernel: posix cpu timer use-after-free may lead to local privilege escalation
https://notcve.org/view.php?id=CVE-2022-2585
It was discovered that when exec'ing from a non-leader thread, armed POSIX CPU timers would be left on a list but freed, leading to a use-after-free. Se descubrió que al ejecutar desde un subproceso no líder, los temporizadores de CPU POSIX armados se dejaban en una lista pero se liberaban, lo que generaba un use-after-free. A use-after-free flaw was found in the Linux kernel’s POSIX CPU timers functionality in the way a user creates and then deletes the timer in the non-leader thread of the program. This flaw allows a local user to crash or potentially escalate their privileges on the system. • https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-2585 https://lore.kernel.org/lkml/20220809170751.164716-1-cascardo@canonical.com/T/#u https://ubuntu.com/security/notices/USN-5564-1 https://ubuntu.com/security/notices/USN-5565-1 https://ubuntu.com/security/notices/USN-5566-1 https://ubuntu.com/security/notices/USN-5567-1 https://www.openwall.com/lists/oss-security/2022/08/09/7 https://access.redhat.com/security/cve/CVE-2022-2585 https://bugzilla.redhat • CWE-416: Use After Free •
CVSS: 8.8EPSS: 0%CPEs: 6EXPL: 5CVE-2022-2588 – Linux Kernel route4_change Double Free Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-2588
It was discovered that the cls_route filter implementation in the Linux kernel would not remove an old filter from the hashtable before freeing it if its handle had the value 0. Se descubrió que la implementación del filtro cls_route en el kernel de Linux no eliminaba un filtro antiguo de la tabla hash antes de liberarlo si su identificador tenía el valor 0. A use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the Linux kernel. This flaw allows a local user to crash the system and possibly lead to a local privilege escalation problem. This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. • https://github.com/Markakd/CVE-2022-2588 https://github.com/veritas501/CVE-2022-2588 https://github.com/BassamGraini/CVE-2022-2588 https://github.com/PolymorphicOpcode/CVE-2022-2588 https://github.com/dom4570/CVE-2022-2588 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-2588 https://lore.kernel.org/netdev/20220809170518.164662-1-cascardo@canonical.com/T/#u https://ubuntu.com/security/notices/USN-5557-1 https://ubuntu.com/security/notices/USN-5560-1 https:/&#x • CWE-415: Double Free CWE-416: Use After Free •
