Description Prasad Pandit 2016-04-19 13:31:52 UTC

Linux kernel built with the USB over IP(CONFIG_USBIP_*) support is vulnerable
to a buffer overflow issue. It could occur while receiving USB/IP packets, when
the size value in the packet is greater actual transfer buffer.

A user/process could use this flaw to crash the remote host via kernel
memory corruption or potentially execute arbitrary code.
