Local privilege escalation via user-switch race
Published Mar 2, 2026 · Updated Mar 2, 2026
Lockscreen bypass in Google Android 14 and 15 allows local users to gain elevated privileges during a user switch. UserController advanced a secure-user switch before SystemUI had prepared and displayed the keyguard, exposing content behind the lockscreen. Exploitation requires no existing privileges or user interaction and depends on winning the user-switch race.
