CVE-2026-72162

CVE-2026-72162 — In the Linux kernel OCFS2 code, a UBSAN array-index-out-of-bounds flaw occurs in ocfs2_sum_rightmost_rec when l_next_free_rec is 0 or exceeds l_count, indexing l_recs[] out of bounds. The root cause is computing i = le16_to_cpu(el->l_next_free_rec) - 1 without validating i. Th...

CVE-2025-39885 ocfs2: fix recursive semaphore deadlock in fiemap call

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix recursive semaphore deadlock in fiemap call syzbot detected a OCFS2 hang due to a recursive semaphore on a FSIOCFIEMAP of the extent list on a specially crafted mmap file. contextswitch kernel/sched/core.c:5357 inline...

CVE-2025-39885

CVE-2025-39885 affects the OCFS2 filesystem in Linux kernels. The vulnerability stems from a recursive semaphore deadlock during fiemap processing of a specially crafted mmap’ed file: ocfs2_fiemap() takes a read lock on ip_alloc_sem, then fiemap_fill_next_extent() accesses the extent list while a...
