CVE-2022-20405Network attack vector

Unauthenticated privilege escalation via undisclosed modem flaw

Published Aug 11, 2022 · Updated Aug 3, 2024

Elevation of privilege in the modem on Google Pixel devices before the 2022-08-05 patch level allows remote attackers to gain elevated access. Google marks the underlying Android bug as nonpublic and provides only an updated binary driver, so the faulty modem operation and attacker-controlled input are undisclosed. The published assessment requires no authentication or user interaction, but the exact privileges gained and reachable modem interface are not stated.
