**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 6.5.4 **Description** The issue is related to a use-after-free error in the ext4 file system driver of the Linux kernel, specifically in the fs/ext4/extents status.c file, related to the `ext4 es insert extent` function. This error is associated with the reuse of previously freed memory. Exploitation of this issue could allow an attacker to impact the confidentiality, integrity, and availability of protected information. **Recommendations** For Linux kernel versions prior to 6.5.4, update to version 6.5.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the ext4 file system to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Linux kernel versions prior to 6.4.12 **Description** The issue is related to the incorrect use of the memory management system interface in the Linux kernel's scatterlist library. This can potentially allow an attacker to impact the integrity and availability of protected information. The `extract user to sg` function in `lib/scatterlist.c` fails to unpin pages in a certain situation, which can lead to problems. **Recommendations** For Linux kernel versions prior to 6.4.12, update to version 6.4.12 or later to resolve the issue. As a temporary workaround, consider restricting access to the `extract user to sg` function in `lib/scatterlist.c` to minimize the risk of exploitation.
