CVE-2023-1206 – kernel: hash collisions in the IPv6 connection lookup table
https://notcve.org/view.php?id=CVE-2023-1206
A hash collision flaw was found in the IPv6 connection lookup table in the Linux kernel’s IPv6 functionality when a user makes a new kind of SYN flood attack. A user located in the local network or with a high bandwidth connection can increase the CPU usage of the server that accepts IPV6 connections up to 95%. • https://bugzilla.redhat.com/show_bug.cgi?id=2175903 https://lists.debian.org/debian-lts-announce/2023/10/msg00027.html https://lists.debian.org/debian-lts-announce/2024/01/msg00004.html https://security.netapp.com/advisory/ntap-20230929-0006 https://www.debian.org/security/2023/dsa-5480 https://www.debian.org/security/2023/dsa-5492 https://access.redhat.com/security/cve/CVE-2023-1206 • CWE-400: Uncontrolled Resource Consumption •
CVE-2023-3389 – Use after free in io_uring in the Linux Kernel
https://notcve.org/view.php?id=CVE-2023-3389
A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Racing a io_uring cancel poll request with a linked timeout can cause a UAF in a hrtimer. We recommend upgrading past commit ef7dfac51d8ed961b742218f526bd589f3900a59 (4716c73b188566865bdd79c3a6709696a224ac04 for 5.10 stable and 0e388fce7aec40992eadee654193cad345d62663 for 5.15 stable). Una vulnerabilidad de use-after-free en el subsistema de io_uring del kernel de Linux puede ser explotada para lograr la escalada de privilegios locales. Ejecutar una solicitud de io_uring cancelar sondeo con un tiempo de espera vinculado puede provocar una UAF en un hrtimer. Recomendamos actualizar al commit anterior ef7dfac51d8ed961b742218f526bd589f3900a59 (4716c73b188566865bdd79c3a6709696a224ac04 para 5.10 stable y 0e388fce7aec40992eadee654193cad345d62663 para 5.15 stable). • http://packetstormsecurity.com/files/174577/Kernel-Live-Patch-Security-Notice-LSN-0097-1.html https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.10.y&id=4716c73b188566865bdd79c3a6709696a224ac04 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.15.y&id=0e388fce7aec40992eadee654193cad345d62663 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ef7dfac51d8ed961b742218f526bd589f3900a59 https://kernel.dance/0e388fce7aec40992eade • CWE-416: Use After Free •
CVE-2023-3212 – kernel: gfs2: NULL pointer dereference in gfs2_evict_inode()
https://notcve.org/view.php?id=CVE-2023-3212
A NULL pointer dereference issue was found in the gfs2 file system in the Linux kernel. It occurs on corrupt gfs2 file systems when the evict code tries to reference the journal descriptor structure after it has been freed and set to NULL.
