CVE-2017-15102 is a vulnerability of currently unknown severity. The tower_probe function in drivers/usb/misc/legousbtower.c in the Linux kernel before 4.8.1 allows local users (who are physically proximate for inserting a crafted USB device) to gain privileges by leveraging a write-what-where condition that occurs after a race condition and a NULL pointer dereference.. EPSS estimates a 0.39% chance of exploitation in the next 30 days.
