GHSA-6723-3R89-PW82
Vulnerability from github – Published: 2025-05-20 18:30 – Updated: 2025-11-14 18:31In 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.
