CVE-2023-53842

Estado: AplazadaSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

ASoC: codecs: wcd-mbhc-v2: fix resource leaks on component remove

The MBHC resources must be released on component probe failure and removal so can not be tied to the lifetime of the component device.

This is specifically needed to allow probe deferrals of the sound card which otherwise fails when reprobing the codec component:
