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

media: mtk-jpeg: Fix null-ptr-deref during unload module

The workqueue should be destroyed in mtk_jpeg_core.c since commit
09aea13ecf6f ("media: mtk-jpeg: refactor some variables"), otherwise
the below calltrace can be easily triggered.
