CVE-2025-39712: media: mt9m114: Fix deadlock in get_frame_interval/set_frame_interval

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: 0.11% (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 0d23b548d71e5d76955fdf1d73addd8f6494f602, 298d1471cf83d5a2a05970e41822a2403f451086, 41b97490a1656bdc7038d6345a84b08d45deafc6.

Low priority for now. Upgrade to Linux Linux 0d23b548d71e5d76955fdf1d73addd8f6494f602, 298d1471cf83d5a2a05970e41822a2403f451086, 41b97490a1656bdc7038d6345a84b08d45deafc6 or later.

In the Linux kernel, the following vulnerability has been resolved: media: mt9m114: Fix deadlock in get_frame_interval/set_frame_interval Getting / Setting the frame interval using the V4L2 subdev pad ops get_frame_interval/set_frame_interval causes a deadlock, as the subdev state is locked in the [1] but also in the driver itself. In [2] it's described that the caller is responsible to acquire and release the lock in this case. Therefore, acquiring the lock in the driver is wrong. Remove the lock acquisitions/releases from mt9m114_ifp_get_frame_interval() and mt9m114_ifp_set_frame_interval().
