CVE-2023-53317

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.2.0-rc1-syzkaller

Description The Linux kernel contains a flaw within the ext4 filesystem related to block bitmap validation. Specifically, the mb find extent function may trigger a warning due to inconsistencies between the expected number of blocks per group and the block bitmap data. This can occur when padding at the end of the block bitmap is not properly set, potentially leading to issues during filesystem operations.

Recommendations Update to a version of the Linux kernel that addresses this issue.
