CVE-2026-74348

CVE-2026-74348 affects the Linux kernel, specifically the ocfs2/dlm path for locking_state debugfs opens. The root cause is that debug_lockres_open() calls dlm_grab(dlm) but ignores its return value; after the last domain unregisters, dlm_grab() can return NULL, yet open stores the raw pointer an...
