CVE-2026-43076

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the OCFS2 file system where the ocfs2 validate inode block() function fails to validate the size of inline data when reading an inode from disk. In cases of filesystem corruption, the i size variable can exceed the actual inline data capacity (id count). This discrepancy leads the ocfs2 dir foreach blk id() function to iterate beyond the inline data buffer, resulting in a use-after-free (UAF) condition—where the system continues to use a pointer after it has been freed—when accessing directory entries via the ocfs2 check dir entry() function.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
