Description
In the Linux kernel 5.3.10, there is a use-after-free (read) in the perf_trace_lock_acquire function (related to include/trace/events/lock.h).
A use-after-free flaw was found when wakeup a waiter was in race in the locks_delete_block in fs/locks.c function in the Linux kernel's filesystem. A local attacker with a special user account (or root) may cause a denial of service, a system crash, or a leak in the internal kernel information.
