Description Sam Fowler 2018-11-19 05:44:09 UTC

In yurex_read in drivers/usb/misc/yurex.c in the Linux kernel before 4.17.7, an out-of-bounds user space access in the read handler of the yurex USB device driver could be used by local attackers to crash the kernel or potentially escalate privileges.
