This CVE record has been marked for NVD enrichment efforts.
Description
In the Linux kernel, the following vulnerability has been resolved:
media: mtk-jpeg: cancel workqueue on release for supported platforms only
Since a recent fix the mtk_jpeg_release function cancels any pending
or running work present in the driver workqueue using
cancel_work_sync function.
Currently, only the multicore based variants use this workqueue and they
have the jpeg_worker platform data field initialized with a workqueue
callback function. For the others, this field value remain NULL by
default.
The cancel_work_sync function is unconditionally called in
mtk_jpeg_release function, even for the variants that do not use the
workqueue. This call generates a WARN_ON print in __flush_work because
the workqueue callback function presence check fails in __flush_work
function (used by cancel_work_sync).
So, to avoid these warnings, call cancel_work_sync only if a workqueue
callback is defined in platform data.
