LIN1025-8470 : Security Advisory - linux - CVE-2026-23252

Created: Mar 19, 2026    Updated: Mar 30, 2026
Found In Version: 10.25.33.2
Severity: Standard
Applicable for: Wind River Linux LTS 25
Component/s: Kernel

Description

In the Linux kernel, the following vulnerability has been resolved:  xfs: get rid of the xchk_xfile_*_descr calls  The xchk_xfile_*_descr 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 could easily exceed that, and Jiaming Zhang found a few places where that can happen with syzbot.  The descriptions are debugging aids and aren't required to be unique, so let's just pass in static strings and eliminate this path to failure. Note this patch touches a number of commits, most of which were merged between 6.6 and 6.14.
