CVE-2026-64358: media: mtk-jpeg: cancel workqueue on release for supported platforms only

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.12% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 0fed0fc34ce734b4b8c2f6a467d38bddcb21dda9, 4c4b4af4a9f278da096f0dbdb6b59594701d29bf, 6.12.96.

Low priority for now. Upgrade to Linux Linux 0fed0fc34ce734b4b8c2f6a467d38bddcb21dda9, 4c4b4af4a9f278da096f0dbdb6b59594701d29bf, 6.12.96 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
