CVE-2017-8071 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
