### Description

In the Linux kernel, the following vulnerability has been resolved:media: v4l: async: Fix NULL pointer dereference in adding ancillary linksIn v4l2_async_create_ancillary_links(), ancillary links are created forlens and flash sub-devices. These are sub-device to sub-device links andif the async notifier is related to a V4L2 device, the source sub-deviceof the ancillary link is NULL, leading to a NULL pointer dereference.Check the notifier's sd field is non-NULL inv4l2_async_create_ancillary_links().[Sakari Ailus: Reword the subject and commit messages slightly.]
