https://notcve.org/view.php?id=CVE-2022-3586
A flaw was found in the Linux kernel’s networking code. A use-after-free was found in the way the sch_sfb enqueue function used the socket buffer (SKB) cb field after the same SKB had been enqueued (and freed) into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing a denial of service. Se ha encontrado un fallo en el código de red del kernel de Linux. Ha sido encontrado un uso de memoria previamente liberada en la forma en que la función sch_sfb enqueue usó el campo cb del búfer de socket (SKB) después de que el mismo SKB había sido puesto en cola (y liberado) en un qdisc hijo. • https://github.com/torvalds/linux/commit/9efd23297cca https://lists.debian.org/debian-lts-announce/2022/11/msg00001.html https://www.zerodayinitiative.com/advisories/upcoming • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2022-2602
io_uring UAF, Unix SCM garbage collection io_uring UAF, recolección de basura Unix SCM This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the io_uring API. The issue results from the improper management of a reference count. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root. Linux suffers from an io_uring use-after-free vulnerability due to broken unix GC interaction. • https://github.com/LukeGix/CVE-2022-2602 https://github.com/kiks7/CVE-2022-2602-Kernel-Exploit https://github.com/th3-5had0w/CVE-2022-2602-Study http://packetstormsecurity.com/files/176533/Linux-Broken-Unix-GC-Interaction-Use-After-Free.html https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-2602 https://ubuntu.com/security/notices/USN-5691-1 https://ubuntu.com/security/notices/USN-5692-1 https://ubuntu.com/security/notices/USN-5693-1 https://ubuntu.com/security/ • CWE-416: Use After Free •
