"Google Patches High-Severity Privilege Escalation Vulnerabilities in Android"

Android’s November 2022 security updates patch over 40 vulnerabilities, including multiple high-severity escalation of privilege bugs.  The first part of the update includes fixes for 17 security defects, 12 of which could lead to escalation of privilege (EoP), three to denial of service (DoS), and two to information disclosure.  All of these are high-severity vulnerabilities impacting Android 10 and newer releases.  Google noted that except for one bug, all of them impact Android 13 as well.  Google stated that the most severe of these issues is a vulnerability in the Framework component that could lead to local escalation of privilege with no additional execution privileges needed.  Google 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 resolves 26 additional issues (one critical and 25 high-severity flaws) in Imagination Technologies, MediaTek, Unisoc, and Qualcomm components.  Google noted that Android devices running a security patch level of 2022-11-05 or later have been patched against all these vulnerabilities.  Google stated that 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.
