CVE-2020-0011

Privilege escalation via unchecked authentication result write

Published Mar 10, 2020 · Updated Aug 4, 2024

Out-of-bounds write in FPC Fingerprint TEE on the Android kernel allows local users with System privileges to elevate privileges. The get_auth_result function in fpc_ta_hw_auth.c writes authentication-result data without checking the destination bounds. Exploitation requires local System execution privileges and no user interaction, and successful memory corruption grants additional permissions.
