Improper input validation in drivers/usb/usbip/stub_rx.c:stub_recv_cmd_submit() in the Linux Kernel when handling CMD_SUBMIT packets allows attackers to cause a denial of service (arbitrary memory allocation) via a specially crafted USB over IP packet.
An upstream fix:
Created kernel tracking bugs for this issue:
Affects: fedora-all [bug 1545617]
This was fixed for fedora with the 4.14.14 stable updates.
This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, 6, and 7, its real-time kernel, Red Hat Enterprise MRG 2, Red Hat Enterprise Linux 7 for ARM 64, and Red Hat Enterprise Linux 7 for Power 9 LE, as the code with the flaw is not enabled and is not built in the products listed.
