Google Patches High-Severity Privilege Escalation Vulnerabilities in Android

Rolling out this week, Android’s November 2022 security updates patch over 40 vulnerabilities, including multiple high-severity escalation of privilege bugs.

The first part of the update, the ‘2022-11-01 patch level’, includes fixes for 17 security defects, 12 of which could lead to escalation of privilege (EoP), three to denial of service (DoS), and two leading to information disclosure.

All of these are high-severity vulnerabilities impacting Android 10 and newer releases. Except for one bug, all of them impact Android 13 as well.

“The most severe of these issues is a high security vulnerability in the Framework component that could lead to local escalation of privilege with no additional execution privileges needed,” Google notes in its advisory.

The internet giant also mentions two additional vulnerabilities addressed as part of the Google Play system updates, namely CVE-2022-2209 (impacting Media framework components) and CVE-2022-20463 (impacting Wi-Fi).

The second part of this month’s Android security update, the ‘2022-11-05 patch level’, resolves 26 additional issues (one critical- and 25 high-severity flaws) in Imagination Technologies, MediaTek, Unisoc, and Qualcomm components.

Android devices running a security patch level of 2022-11-05 or later have been patched against all these vulnerabilities.

An additional set of five issues were resolved with the November 2022 Pixel security updates. These include two high-severity bugs in the Titan M chip and three medium-severity flaws in Qualcomm closed-source components.
