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 •

08 May 2023 — In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled. A use-after-free vulnerability was found in the Netfilter subsystem of the Linux kernel when processing batch requests to update nf_tables configuration. This vulnerability can be abused to perform arbitrary reads and write... • https://github.com/oferchen/POC-CVE-2023-32233 • CWE-416: Use After Free •
