CVE-2022-49538

Estado: ModificadaMedia (5.5)—

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

ALSA: jack: Access input_dev under mutex

It is possible when using ASoC that input_dev is unregistered while calling snd_jack_report, which causes NULL pointer dereference. In order to prevent this serialize access to input_dev using mutex lock.
