Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel up to 6.1.10. This affects the function lru_gen_migrate_mm. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: mm: multi-gen LRU: fix crash during cgroup migration lru_gen_migrate_mm() assumes lru_gen_add_mm() runs prior to itself. This isn't true for the following scenario: CPU 1 CPU 2 clone() cgroup_can_fork() cgroup_procs_write() cgroup_post_fork() task_lock() lru_gen_migrate_mm() task_unlock() task_lock() lru_gen_add_mm() task_unlock() And when the above happens, kernel crashes because of linked list corruption (mm_struct->lru_gen.list).

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2023-52940 since 08/21/2024. Technical details are known, but no exploit is available.

Upgrading to version 6.1.11 eliminates this vulnerability. Applying the patch 04448022311cebd30969d3aebdde765f1258b360/de08eaa6156405f2e9369f06ba5afae0e4ab3b62 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.
