CVE-2022-4283 – X.Org Server XkbCopyNames Double Free Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-4283
A vulnerability was found in X.Org. This security flaw occurs because the XkbCopyNames function left a dangling pointer to freed memory, resulting in out-of-bounds memory access on subsequent XkbGetKbdByName requests.. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions. Se encontró una vulnerabilidad en X.Org. Este fallo de seguridad se produce porque la función XkbCopyNames dejó un puntero colgante a la memoria liberada, lo que provocó un acceso a la memoria fuera de los límites en solicitudes posteriores de XkbGetKbdByName. • https://access.redhat.com/security/cve/CVE-2022-4283 https://bugzilla.redhat.com/show_bug.cgi?id=2151761 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5NELB7YDWRABYYBG4UPTHRBDTKJRV5M2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DXDF2O5PPLE3SVAJJYUOSAD5QZ4TWQ2G https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/Z67QC4C3I2FI2WRFIUPEHKC36J362MLA https://security.gentoo.org/glsa/202305-30 https://www • CWE-416: Use After Free •

CVE-2022-3586 – Linux Kernel Net Scheduler Use-After-Free Information Disclosure Vulnerability
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 •
