AI-suggested

A fix is available in the Linux kernel as per commits 570a6aaf6b52c6ec098f4811cdb52b1496f13d15 and 4a724bcf5d703e18957397914d79156fa2cf1174. Users and administrators should update to a patched kernel version that includes these commits to mitigate the race condition. No other mitigation or workaround is indicated.

Description

CVE-2026-97941 is a race condition vulnerability in the Linux kernel's slab allocator, specifically in the __slab_try_return_freelist() function. The flaw arises from improper locking around slab list manipulation, leading to potential list corruption and kernel panic. This vulnerability can cause a fatal kernel exception and system crash due to a classic ABA problem in concurrent slab object management.
