CVE-2023-1206 – kernel: hash collisions in the IPv6 connection lookup table
https://notcve.org/view.php?id=CVE-2023-1206
30 Jun 2023 — 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%. It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service. ... • https://bugzilla.redhat.com/show_bug.cgi?id=2175903 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm 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
28 Jun 2023 — 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).

CVE-2023-3212 – kernel: gfs2: NULL pointer dereference in gfs2_evict_inode()
https://notcve.org/view.php?id=CVE-2023-3212
23 Jun 2023 — 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. A privileged local user could use this flaw to cause a kernel panic. A NULL pointer dereference flaw was found in the gfs2 file system in the Linux kernel.

CVE-2023-2124 – kernel: OOB access in the Linux kernel's XFS subsystem
https://notcve.org/view.php?id=CVE-2023-2124
15 May 2023 — An out-of-bounds memory access flaw was found in the Linux kernel’s XFS file system in how a user restores an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or potentially escalate their privileges on the system. It was discovered that the XFS file system implementation in the Linux kernel did not properly perform metadata validation when mounting certain images. An attacker could use this to specially craft a file system image that, when mounted, could cause a de... • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/fs/xfs/xfs_buf_item_recover.c?h=v6.4-rc1&id=22ed903eee23a5b174e240f1cdfa9acf393a5210 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
