CVE-2018-16276

Published: 31 August 2018

An issue was discovered in yurex_read in drivers/usb/misc/yurex.c in the Linux kernel before 4.17.7. Local attackers could use user access read/writes with incorrect bounds checking in the yurex USB driver to crash the kernel or potentially escalate privileges.

From the Ubuntu security team

It was discovered that the YUREX USB device driver for the Linux kernel did not properly restrict user space reads or writes. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
