The first part of this month’s Android security update arrives on devices as the 2022-01-01 security patch level, addressing a total of 16 security holes in three components, namely Framework, Media Framework, and System.
The second part of the update – the 2022-01-05 security patch level – includes fixes for 19 security defects in Android runtime, Kernel components, MediaTek components, Unisoc components, Qualcomm components, and Qualcomm closed-source components.
According to Google, an Android runtime flaw, which impacts devices running Android 12, is the most important of these bugs. Tracked as CVE-2021-0959, the vulnerability leads to elevation of privilege.
“The most severe of these issues is a high security vulnerability in the Android runtime component that could enable a local attacker to bypass memory restrictions in order to gain access to additional permissions,” Google says.

For Pixel devices, a security patch level of 2022-01-05 addresses 10 other security holes as well. Per Google’s advisory, these affect Pixel components, Qualcomm components, and Qualcomm closed-source components.
