Description

In the Linux kernel, the following vulnerability has been resolved: ASoC: qcom: q6apm-lpass-dai: Fix multiple graph opens As prepare can be called mulitple times, this can result in multiple graph opens for playback path. This will result in a memory leaks, fix this by adding a check before opening.

Attack-Flow Graph

Executive Summary

This vulnerability exists in the Linux kernel component ASoC: qcom: q6apm-lpass-dai. It occurs because the 'prepare' function can be called multiple times, which leads to multiple graph opens for the playback path.

These multiple graph opens cause a memory leak, as the system opens resources repeatedly without proper checks.

The issue was fixed by adding a check before opening the graph to prevent multiple opens.

Impact Analysis

This vulnerability can lead to memory leaks in the Linux kernel's audio subsystem related to Qualcomm hardware playback paths.

Memory leaks can degrade system performance over time, potentially causing instability or crashes if the leaked memory accumulates.

Mitigation Strategies

The vulnerability in the Linux kernel related to multiple graph opens in the qcom q6apm-lpass-dai component has been fixed by adding a check before opening to prevent memory leaks.

To mitigate this vulnerability, you should update your Linux kernel to the version that includes this fix.
