A race condition vulnerability in the Linux kernel's NFC LLCP socket handling was resolved. The flaw involved concurrent unlinking and releasing of the same child socket due to improper synchronization between socket release and accept dequeue operations, leading to potential use-after-free or NULL pointer dereference. The fix replaces a bottom-half lock with a process-context lock, defers final resource release to a workqueue to avoid sleeping in atomic context, and adds safeguards to prevent object resurrection and listener hangs. The vulnerability affects the NFC LLCP socket lifecycle and was addressed with multiple synchronization and lifecycle management improvements.
