CVE-2022-20181Network attack vector

Service interruption via undisclosed modem flaw

Published Jun 15, 2022 · Updated Aug 3, 2024

Denial of service in the modem component of Google Android on supported Pixel devices allows remote attackers to interrupt service. Google marks the Android bug and associated binary-driver update as nonpublic, so the modem operation performed incorrectly on untrusted traffic is undisclosed. No privileges or user interaction are required, but public sources do not distinguish whether the interruption is a crash, hang, or reboot.
