CVE-2026-23250

In the Linux kernel, the following vulnerability has been resolved: xfs: check return value of xchkscrubcreatesubord Fix this function to return NULL instead of a mangled ENOMEM, then fix the callers to actually check for a null pointer and return ENOMEM. Most of the corrections here are for code...

CVE-2026-23249

In the Linux kernel, the following vulnerability has been resolved: xfs: check for deleted cursors when revalidating two btrees The free space and inode btree repair functions will rebuild both btrees at the same time, after which it needs to evaluate both btrees to confirm that the corruptions a...

CVE-2026-23252 xfs: get rid of the xchk_xfile_*_descr calls

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. Some of them cou...

CVE-2026-23252

The CVE-2026-23252 issue affects the Linux kernel XFS code. The root cause is the xchk_xfile_*_descr macros calling kasprintf, which could fail to allocate memory when formatting strings larger than the non‑no-fail limit. The patch removes this path by passing static strings instead, eliminating ...

CVE-2026-23251

In the Linux kernel, the following vulnerability has been resolved: xfs: only call xfarray,blobdestroy if we have a valid pointer Only call the xfarray and xfblob destructor if we have a valid pointer, and be sure to null out that pointer afterwards. Note that this patch fixes a large number of...

CVE-2026-23251 xfs: only call xf{array,blob}_destroy if we have a valid pointer

In the Linux kernel, the following vulnerability has been resolved: xfs: only call xfarray,blobdestroy if we have a valid pointer Only call the xfarray and xfblob destructor if we have a valid pointer, and be sure to null out that pointer afterwards. Note that this patch fixes a large number of...

CVE-2026-23251

The CVE-2026-23251 issue affects the Linux kernel XFS code: destructors xfarray/xfblob were invoked on possibly-invalid pointers. The patch ensures xf{array,blob}_destroy is only called for a valid pointer and clears it afterwards, improving memory safety. The fix was merged in commits between 6....

CVE-2026-23250

CVE-2026-23250 is a Linux kernel vulnerability in the XFS code path. The issue arises from not checking the return value of xchk_scrub_create_subord, which could yield an ENOMEM mangling the flow. The fix updates xchk_scrub_create_subord to return NULL on allocation failure and adjusts callers to...

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...
