CVE-2025-22079

In the Linux kernel, the following vulnerability has been resolved:

ocfs2: validate l_tree_depth to avoid out-of-bounds access

The l_tree_depth field is 16-bit (__le16), but the actual maximum depth is limited to OCFS2_MAX_PATH_DEPTH.

Add a check to prevent out-of-bounds access if l_tree_depth has an invalid value, which may occur when reading from a corrupted mounted disk [1].

Red Hat products are not impacted by this flaw because the OCFS2 filesystem driver is not built or enabled in supported Red Hat Enterprise Linux kernels. In upstream environments, mounting a maliciously crafted or corrupted filesystem volume could trigger out-of-bounds memory access, potentially leading to a kernel crash. Because the vulnerable module is absent from all supported configurations, Red Hat deployments face no operational risk.
