CVE-2026-23249

Summary (CVE-2026-23249) : In Linux kernel XFS, during free-space and inode btree repair, revalidation calls xchk_allocbt for BNOBT and CNTBT can race: the first call nullifies the CNTBT cursor, causing a NULL dereference on the second revalidation. The fix changes the control flow so CNTBT curso...
