CVE-2022-32618

Physical-access privilege escalation via miscalculated Type-C buffer

Published Nov 8, 2022 · Updated May 1, 2025

Out-of-bounds write in MediaTek typec on affected Android 11.0 through 13.0 chipsets allows physically proximate attackers to elevate privileges. The typec component miscalculates a destination buffer size and consequently writes data beyond the allocated boundary. Physical access is required, but no initial execution privileges or user interaction is needed; successful exploitation grants elevated privileges.
