CVE-2024-44098

Local privilege escalation via LWIS double free

Published Oct 25, 2024 · Updated Oct 25, 2024

Double free in LWIS on Google Android Pixel devices allows local users to escalate privileges without user interaction. lwis_device_event_states_clear_locked in lwis_event.c frees the same event-state allocation twice during cleanup. Local access is required, but no additional execution privileges or user action is needed; successful exploitation grants elevated device privileges.
