CVE-2017-17975 is a medium-severity use after free vulnerability in Linux kernel, published on 30 Dec 2017. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

Use-after-free in the usbtv_probe function in drivers/media/usb/usbtv/usbtv-core.c in the Linux kernel through 4.14.10 allows attackers to cause a denial of service (system crash) or possibly have unspecified other impact by triggering failure of audio registration, because a kfree of the usbtv data structure occurs during a usbtv_video_free call, but the usbtv_video_fail label's code attempts to both access and free this data structure.
