CVE-2025-39712

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> media: mt9m114: Fix deadlock in get_frame_interval/set_frame_interval<br /> <br /> Getting / Setting the frame interval using the V4L2 subdev pad ops<br /> get_frame_interval/set_frame_interval causes a deadlock, as the<br /> subdev state is locked in the [1] but also in the driver itself.<br /> <br /> In [2] it&amp;#39;s described that the caller is responsible to acquire and<br /> release the lock in this case. Therefore, acquiring the lock in the<br /> driver is wrong.<br /> <br /> Remove the lock acquisitions/releases from mt9m114_ifp_get_frame_interval()<br /> and mt9m114_ifp_set_frame_interval().<br /> <br /> [1] drivers/media/v4l2-core/v4l2-subdev.c - line 1129<br /> [2] Documentation/driver-api/media/v4l2-subdev.rst
