CVE-2021-0362

Local privilege escalation via aee stack overflow

Published Feb 2, 2021 · Updated Aug 3, 2024

Stack buffer overflow in the aee component of Google Cloud Android 11 allows local users to gain System execution privileges. The component writes beyond a stack buffer while processing undisclosed local input, corrupting memory; neither the affected routine nor the missing bounds operation is public. Exploitation requires existing System execution privileges and needs no user interaction, limiting exposure to code already running locally on an affected device.
