Positive Technologies (AI Summary)

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A use-after-free issue exists in the Linux kernel's media subsystem, specifically within the mtk-jpeg driver. The issue occurs due to an uncanceled work item (mtk jpeg job timeout work) when the module is removed. The sequence involves binding the work item in mtk jpeg probe, potentially starting it in mtk jpeg dec device run or mtk jpeg enc device run, and then freeing the associated memory in mtk jpeg remove before the work item completes, leading to a use-after-free condition. The fix involves canceling the work item before cleanup in the mtk jpeg remove function.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
