CVE-2017-16530 : What You Need to Know

In versions prior to 4.13.6 of the Linux kernel, the uas driver allows local users to provoke a denial of service or potentially cause other unknown effects by exploiting a specifically designed USB device. This vulnerability is linked to the files uas-detect.h and uas.c within the drivers/usb/storage directory.

Understanding CVE-2017-16530
