This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

media: v4l: async: Fix NULL pointer dereference in adding ancillary links

In v4l2_async_create_ancillary_links(), ancillary links are created for

lens and flash sub-devices. These are sub-device to sub-device links and

if the async notifier is related to a V4L2 device, the source sub-device

of the ancillary link is NULL, leading to a NULL pointer dereference.

Check the notifier's sd field is non-NULL in

v4l2_async_create_ancillary_links().

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
