CVE-2022-50305

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ASoC: sof_es8336: fix possible use-after-free in sof_es8336_remove()<br /> <br /> sof_es8336_remove() calls cancel_delayed_work(). However, that<br /> function does not wait until the work function finishes. This<br /> means that the callback function may still be running after<br /> the driver&amp;#39;s remove function has finished, which would result<br /> in a use-after-free.<br /> <br /> Fix by calling cancel_delayed_work_sync(), which ensures that<br /> the work is properly cancelled, no longer running, and unable<br /> to re-schedule itself.
