Local privilege escalation via missing bounds check
Published Feb 4, 2021 · Updated Aug 3, 2024
Memory corruption in mtkpower in Android 10 and 11 allows local users with System execution privileges to elevate privileges. The component omits a bounds check before a memory access, but the affected function and attacker-controlled input are undisclosed. Exploitation requires existing System execution privileges and no user interaction; the published record identifies privilege escalation but no narrower post-exploitation capability.
