Linux Kernel Vulnerability in WCD938X Codec Handling

CVE-2023-53666

What is CVE-2023-53666?

In the Linux kernel, a vulnerability exists within the ASoC codecs, specifically related to the WCD938X codec. The vulnerability arises from the failure to properly handle the initialization of the multi-button headset connector (MBHC). This oversight can lead to dereferencing an error pointer during jack configuration, potentially causing an inability to manage kernel paging requests. Effective error handling measures should be implemented to prevent system instability and ensure secure operation of audio codec functionality.
