Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a potential NULL pointer dereference in the Linux kernel, specifically in the ASoC (Audio System on Chip) component, which is used for audio processing. The problem arises because not all entries of the
struct sof conn stream declare a normal link string, which is a non-SOF (Sound Open Firmware) direct link string. This is particularly relevant for System-on-Chip (SoC) designs that support only SOF paths and do not support both direct and SOF use cases. For example, the MT8188 SoC does not have a normal link string in any of its sof conn stream entries. To prevent possible NULL pointer kernel panics (KPs), a NULL check for the normal link string has been added.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
