Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the Linux kernel, where the
struct v4l2 async notifier has several list head members, but only waiting list and done list are initialized. The notifier entry is kept 'zeroed', leading to an uninitialized list head. This results in a NULL-pointer dereference if csi2 async register() fails, for example, when the node for the remote endpoint is disabled, and returns -ENOTCONN. The following calls to v4l2 async nf unregister() result in a NULL pointer dereference. The fix involves adding the missing list head initializer.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
