CVE-2025-37971

Kernel crash via uninitialized camera device pointer

Published May 20, 2025 · Updated May 11, 2026

NULL-pointer dereference in the bcm2835 camera driver in Linux 6.10 allows local users with administrative privileges to crash the kernel. The mmal_init path passes dev->v4l2_dev.dev to vchiq_mmal_init even though bcm2835_mmal_probe never initializes that device pointer. Triggering requires root or CAP_SYS_ADMIN access to bind or unbind the driver through sysfs, and successful triggering interrupts the entire system.
