The race was caused by accessing shared context fields without always holding uring_lock. The fix ensures the function only proceeds if it can safely acquire the mutex. This mitigates potential information leaks or instability during concurrent io_uring activity and fdinfo inspection. The vulnerability is only exploitable by processes with high privileges, as it requires access to io_uring resources, use of IORING_REGISTER_RESIZE_RINGS, and the ability to read from /proc/<pid>/fdinfo/<fd>, all of which are typically restricted to privileged users or the process owner.", "threat_severity": "Moderate"}
