CVE-2026-23250

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

xfs: check return value of xchk_scrub_create_subord

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 merged between 6.2 and 6.10.
