Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)

Description: The issue is related to an uninitialized pointer dmactl in the lpass get dmactl handle function of the Linux kernel's ASoC qcom component. When the driver id dai id is invalid, the pointer dmactl is not assigned a value and contains a garbage value, which can cause the null check to fail. This can lead to a denial of service. The fix involves initializing dmactl to NULL. The vulnerability may allow an attacker to cause a denial of service.

Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
