Description Marcus Meissner 2017-04-24 09:32:53 UTC 
CVE-2017-8071

drivers/hid/hid-cp2112.c in the Linux kernel 4.9.x before 4.9.9 uses a spinlock
without considering that sleeping is possible in a USB HID request callback,
which allows local users to cause a denial of service (deadlock) via unspecified
vectors.
