Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: sof_es8336: fix possible use-after-free in sof_es8336_remove() sof_es8336_remove() calls cancel_delayed_work(). However, that function does not wait until the work function finishes. This means that the callback function may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling cancel_delayed_work_sync(), which ensures that the work is properly cancelled, no longer running, and unable to re-schedule itself.
