Local privilege escalation via missing GNSS bounds check
Published Apr 1, 2024 · Updated Aug 1, 2024
Improper input validation in MediaTek GNSS on affected chipsets allows local users with System privilege to escalate privileges. The GNSS component omits a bounds check, but MediaTek has not disclosed the unchecked input, memory operation, or affected function. Exploitation requires existing System execution privilege and no user interaction; the resulting elevated privilege level is undisclosed.
