CVE-2016-3955: Buffer Overflow
Last updated 24 July 2024
Other sources
Linux kernel built with the USB over IP(CONFIGUSBIP) 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.

The usbiprecvxbuff function in drivers/usb/usbip/usbipcommon.c in the Linux kernel before 4.5.3 allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact via a crafted length value in a USB/IP packet.
