Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a null pointer dereference error in the ALSA component of the Linux kernel. This error occurs when assigning a stream, particularly when a user attempts to assign a COUPLED stream, which is not blocked by AudioDSP drivers. The supplied substream instance may be a stub, leading to a null pointer dereference when code-loading. This could 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.
