Background
The ASoC (Audio System on Chip) mxs is a component of the Linux Kernel. It provides support for audio devices using the mxs_sgtl5000 driver. The mxs_sgtl5000 driver is responsible for managing the SGTL5000 audio codec found on various MXS-based platforms. This vulnerability affects the mxs_sgtl5000_probe function in the mxs driver. The function is responsible for initializing and probing the SGTL5000 audio codec. The vulnerability lies in the error handling of this function.
Vulnerability Detail
The vulnerability in mxs_sgtl5000_probe function can lead to potential security issues. When an error occurs during the initialization or probing of the SGTL5000 audio codec, the error handling in the function is not properly implemented. This can result in undefined behavior or system crashes. An attacker may be able to exploit this vulnerability to execute arbitrary code or cause a denial of service. The vulnerability was introduced in version v3.5 of the Linux Kernel and has been fixed in version v5.15.33.
How To Fix
