Description

In the Linux kernel, the following vulnerability has been resolved: soundwire: qcom: fix storing port config out-of-bounds The 'qcom_swrm_ctrl->pconfig' has size of QCOM_SDW_MAX_PORTS (14), however we index it starting from 1, not 0, to match real port numbers. This can lead to writing port config past 'pconfig' bounds and overwriting next member of 'qcom_swrm_ctrl' struct. Reported also by smatch: drivers/soundwire/qcom.c:1269 qcom_swrm_get_port_config() error: buffer overflow 'ctrl->pconfig' 14 <= 14

Executive Summary

This vulnerability is a buffer overflow in the Linux kernel's soundwire driver for Qualcomm hardware. Specifically, the 'qcom_swrm_ctrl->pconfig' array has a size of 14, but the code indexes it starting from 1 instead of 0, which can cause writes beyond the array bounds. This leads to overwriting adjacent memory in the 'qcom_swrm_ctrl' structure.

Impact Analysis

The buffer overflow can cause memory corruption in the kernel, potentially leading to system instability, crashes, or exploitation by attackers to execute arbitrary code with kernel privileges.
