Linux Kernel OCFS2 Out-of-Bounds Access Vulnerability in Tree Depth Validation

Vulnerability

A vulnerability in the Linux kernel's OCFS2 file system allows for out-of-bounds access due to improper validation of the l_tree_depth field. This field is 16-bit (__le16), but the maximum depth is limited to OCFS2_MAX_PATH_DEPTH. The vulnerability may arise when reading from a corrupted mounted disk.

Impact

The vulnerability could lead to out-of-bounds memory access, potentially causing memory corruption or allowing for arbitrary code execution.
