Description Andrej Nemec 2017-11-22 11:49:07 UTC

The hdpvr_probe function in drivers/media/usb/hdpvr/hdpvr-core.c in the Linux kernel through 4.13.11 allows local users to cause a denial of service (improper error handling and system crash) or possibly have unspecified other impact via a crafted USB device.
