Google on Monday announced that the Android security updates for February 2022 patch a total of 36 vulnerabilities.

The first part of the update arrives on devices as the 2022-02-01 patch level and delivers fixes for 15 security holes in three components, namely Framework, Media framework, and System.

The most severe of these issues is CVE-2021-39675, a critical vulnerability in the System component that could be exploited to elevate privileges, Google notes in its advisory.

“The most severe of these issues is a critical security vulnerability in the System component that could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation,” the company explains.

All of the remaining 14 issues in this patch level are rated high severity. Five of them impact Framework (four elevation of privilege and one information disclosure bug), four were fixed in the Media framework (two elevation of privilege and two information disclosure flaws), and five were identified in the System component (four elevation of privilege and one DoS vulnerability).

Android devices running a security patch of 2022-02-05 or later are protected against all of these flaws and against previously patched issues.
