CVE-2019-3901

CVE-2019-3901 describes a race condition in perf_event_open() that can leak data from setuid processes. The root cause is that cred_guard_mutex is not held during the ptrace_may_access() check, allowing a target task to execve() with setuid execution before perf_event_alloc() attaches, bypassing ...
