Background

The android.hardware.graphics.composer@2.4-service package is a component of the Android ecosystem that provides functionality for graphics composition. It includes the ComposerCommandEngine.h file, which is responsible for executing commands related to setting the client target. This package is vulnerable to an out of bounds read in the executeSetClientTarget function, which can result in local information disclosure. This vulnerability requires system execution privileges to exploit and does not require user interaction.

Vulnerability Detail

The executeSetClientTarget function in ComposerCommandEngine.h lacks a bounds check, leading to a possible out of bounds read. An attacker with system execution privileges can exploit this vulnerability to disclose local information. The impact of this vulnerability can vary depending on the sensitive data that can be accessed through the out of bounds read. It is important to note that user interaction is not required for exploitation.
