Description
A vulnerability in the Linux kernel ASoC driver for the nau8821 codec could cause a kernel crash if the driver is unloaded while a delayed jack detection work is pending. The issue arises because the delayed work is not properly canceled or waited on before the component is removed, leading to a page fault when the work eventually executes.
