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().
