Description

In the Linux kernel, the following vulnerability has been resolved: ASoC: qcom: Fix sc7280 lpass potential buffer overflow Case values introduced in commit 5f78e1fb7a3e ("ASoC: qcom: Add driver support for audioreach solution") cause out of bounds access in arrays of sc7280 driver data (e.g. in case of RX_CODEC_DMA_RX_0 in sc7280_snd_hw_params()). Redefine LPASS_MAX_PORTS to consider the maximum possible port id for q6dsp as sc7280 driver utilizes some of those values. Found by Linux Verification Center (linuxtesting.org) with SVACE.

Analysis

In the Linux kernel, the following vulnerability has been resolved: ASoC: qcom: Fix sc7280 lpass potential buffer overflow Case values introduced in commit 5f78e1fb7a3e ("ASoC: qcom: Add driver. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. This Out-of-bounds Write vulnerability could allow attackers to write data beyond allocated buffer boundaries leading to code execution or crashes.

Technical Context

This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. In the Linux kernel, the following vulnerability has been resolved: ASoC: qcom: Fix sc7280 lpass potential buffer overflow Case values introduced in commit 5f78e1fb7a3e ("ASoC: qcom: Add driver support for audioreach solution") cause out of bounds access in arrays of sc7280 driver data (e.g. in case of RX_CODEC_DMA_RX_0 in sc7280_snd_hw_params()). Redefine LPASS_MAX_PORTS to consider the maximum possible port id for q6dsp as sc7280 driver utilizes some of those values. Found by Linux Verification Center (linuxtesting.org) with SVACE. Affected products include: Linux Linux Kernel, Debian Debian Linux.

Affected Products

Linux Linux Kernel, Debian Debian Linux.

Remediation

A vendor patch is available. Apply the latest security update as soon as possible. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).
