CVE-2026-64358

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