  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: v4l2-async: avoid deleting unlinked ASC entry on link error\n\nv4l2_async_match_notify() creates ancillary media links before adding\nasc-\u003easc_subdev_entry to sd-\u003easc_list.\n\nIf ancillary link creation fails, the function jumps to\nerr_call_unbind while asc_subdev_entry has not been linked yet. Async\nconnections are zero-allocated, so the list entry still has NULL next\nand prev pointers on this path. Calling list_del() on it can therefore\ndereference NULL instead of returning the original link creation error.\n\nDo not delete asc_subdev_entry from err_call_unbind. There is no list\ninsertion to undo on this path; the bound callback and sub-device\nregistration are the operations that need to be rolled back.",
