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

Description A flaw exists in the Linux kernel related to soundwire Qualcomm configurations. Specifically, the qcom swrm ctrl->pconfig buffer can experience an out-of-bounds write due to indexing starting from 1 instead of 0. This can lead to overwriting adjacent memory within the qcom swrm ctrl structure. The issue was reported by smatch in the qcom swrm get port config() function within the drivers/soundwire/qcom.c file.

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