Google this week announced the release of patches for 39 vulnerabilities as part of the March 2022 security update for Android.
The most serious vulnerability is CVE-2021-39708, a remotely exploitable elevation of privilege issue identified in the System component.
“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,” Google notes in its advisory.
The first part of this month’s set of patches arrives on devices as the 2022-03-01 security patch level and addresses CVE-2021-39708, along with 17 other bugs.
A total of 10 security issues were resolved in the System component (nine elevation of privilege and one information disclosure vulnerability), six flaws were resolved in Framework (four elevation of privilege and two denial of service bugs), one was patched in Android runtime (elevation of privilege) and one in Media Framework (information disclosure).
The March 2022 Android security updates also resolve 21 vulnerabilities as part of the 2022-03-05 security patch level.
These impact Framework, Kernel components, MediaTek components, Qualcomm components, and Qualcomm closed-source components.
Two other Google Play system updates addressed vulnerabilities in media codecs and permission controller components, Google says.
On Google Pixel devices, a patch level of 2022-03-05 or later addresses all of these vulnerabilities along with 41 other security holes that affect Kernel components (13 flaws), Pixel (26), Qualcomm components (1) and Qualcomm closed-source components (1).
