A high-severity vulnerability (CVE-2025-40203) in the Linux kernel related to the listmount function has been resolved. The issue involved calling path_put() while holding the namespace semaphore, which could lead to serious kernel stability and security problems if the last reference was released improperly. This flaw has been fixed by modifying listmount() to avoid calling path_put() under the namespace semaphore.
