Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A NULL pointer dereference issue was found in the Linux kernel, specifically in the bcm2835-camera module. This occurred because the
dev->v4l2 dev was not initialized before being passed to vchiq mmal init. The issue arose from a commit that changed mmal init to pass dev->v4l2 dev.dev to vchiq mmal init without initializing dev->v4l2 dev. The device pointer could be set using v4l2 device register, but this would require additional changes due to other effects.Recommendations
To resolve this issue, initialize
dev->v4l2 dev.dev during bcm2835 mmal probe. As a temporary workaround, consider restricting access to the bcm2835-camera module until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
