CVE-2026-23252

In the Linux kernel, the following vulnerability has been resolved: xfs: get rid of the xchkxfiledescr calls The xchkxfiledescr macros call kasprintf, which can fail to allocate memory if the formatted string is larger than 16 bytes or whatever the nofail guarantees are nowadays.

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...
