Background

The platform/frameworks/base package is a fundamental component of the Android operating system. It provides core functionalities and APIs for various system services and applications. One of its key features is the PackageManager, which manages the installation, upgrade, and removal of applications on an Android device. This package is vulnerable to a permanent denial of service (DoS) attack when using the setPackagesSuspended method with invalid SuspendParams.launcherExtras.

Vulnerability Detail

The vulnerability arises from a flaw in the saveToXml function of PersistableBundle.java. By providing invalid data to the SuspendParams.launcherExtras parameter, an attacker can trigger a local persistent DoS attack without requiring additional execution privileges or user interaction. This vulnerability affects Android versions 11, 12, 12L, and 13. Exploitation of this vulnerability can lead to the unavailability of critical system services and applications, causing significant disruption to the device's functionality.
