Google specialists have released security updates for Android versions 10, 11 and 12 for March 2022, eliminating three critical vulnerabilities. One of the problems affects all devices running the latest version of the mobile OS.

One of the problems (CVE-2021-39708) is contained in the Android System component and is a privilege escalation vulnerability that does not require user interaction or additional execution privileges. Two other critical vulnerabilities (CVE-2021-1942 and CVE-2021-35110) affect closed source components on Qualcomm-based devices.
