CVE-2026-64358

CVE-2026-64358 concerns the Linux kernel driver media: mtk-jpeg. The issue arises because mtk_jpeg_release unconditionally calls cancel_work_sync on a workqueue, even for variants that do not use a workqueue (where jpeg_worker platform data is NULL). This leads to a WARN_ON in __flush_work due to...
