Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw within the ASoC Qualcomm q6apm-lpass-dais component. Specifically, a NULL pointer dereference can occur if the initialization of the source graph fails. This happens when the graph is closed and
dai data->graph[dai->id] is assigned NULL, but the preparation for the sink graph continues, leading to a NULL pointer exception during the q6apm lpass dai prepare() function call. This can result in errors during APM port startup and potentially system instability.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
