CVE-2025-37971 Information

Description

In the Linux kernel the following vulnerability has been resolved:

staging: bcm2835-camera: Initialise dev in v4l2_dev

Commit 42a2f6664e18 (\staging: vc04_services: Move global g_state to vchiq_state) changed mmal_init to pass dev->v4l2_dev.dev to vchiq_mmal_init however nothing iniitialised dev->v4l2_dev so we got a NULL pointer dereference.

Set dev->v4l2_dev.dev during bcm2835_mmal_probe. The device pointer could be passed into v4l2_device_register to set it however that also has other effects that would need additional changes.
