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.
A flaw was found in the Linux kernel's media component, specifically within the `mtk-jpeg` driver. An internal function attempts to cancel a background task even when that task is not active on certain system configurations. This can lead to the system logging warning messages, potentially causing minor system instability or unexpected behavior. This issue does not result in critical security impacts such as data compromise or unauthorized code execution.
