A use-after-free vulnerability in the Linux kernel's NFSD component during client teardown has been resolved. The flaw involves improper handling of lock owners when a client is destroyed, leading to a NULL dereference in remove_blocked_locks(). This occurs because __destroy_client() does not hold the necessary lock or reference while walking the owner table, allowing a blocked lock owner to be freed concurrently by the per-net laundromat. This vulnerability has been addressed by ensuring proper locking and reference management during client teardown.
