Local privilege escalation via carrier restriction bypass
Published Oct 11, 2023 · Updated Sep 18, 2024
Elevation of privilege in Google Android kernel allows local users to bypass carrier restrictions through an oobconfig logic flaw. The oobconfig component applies carrier-restriction checks incorrectly, allowing a local process to reach operations intended for higher-privileged contexts. Exploitation requires local access but no user interaction or additional execution privileges, and results in privilege escalation rather than a network compromise.
