CVE-2024-20125

Local privilege escalation via vdec bounds-check omission

Published Dec 2, 2024 · Updated Dec 3, 2024

Out-of-bounds write in MediaTek vdec on affected Android 13.0 and 14.0 chipsets allows local users to escalate privileges. The vdec component omits a bounds check before a write, allowing data to be written beyond its intended buffer. Exploitation requires prior System privilege and no user interaction; successful memory corruption grants higher local privileges.
