CVE-2015-7566

A flaw was found in the way the Linux kernel visor driver handles certain invalid USB device descriptors. The driver assumes that the device always has at least one bulk OUT endpoint. By using a specially crafted USB device (without a bulk OUT endpoint), an unprivileged user with physical access could trigger a kernel NULL-pointer dereference and cause a system panic (denial of service).

This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, 6 as the code with the flaw is not present in the products listed.

This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 7, and MRG-2. This has been rated as having Low security impact and is not currently planned to be addressed in future updates.
