CVE-2024-41049 is a race-condition use-after-free vulnerability in the Linux kernel file-locking subsystem's posix_lock_inode path. The request pointer can be changed to reference a lock entry newly added to an inode lock list. Before trace_posix_lock_inode() executes, a concurrent task can free that lock entry, causing the tracepoint to access freed memory. The upstream correction moves the tracepoint invocation inside the applicable spinlock, preserving the lock entry's lifetime through tracing.
