**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** A issue in the Linux kernel has been identified where the input dev can be unregistered while calling snd jack report when using ASoC, leading to a NULL pointer dereference. This occurs due to lack of serialization in access to input dev. **Recommendations** To resolve this issue, apply a patch that implements a mutex lock to serialize access to input dev, preventing the NULL pointer dereference.
