+ <h1>Problem Description:</h1>
+ <p>A programming error in the ure(4) device driver caused some Realtek USB
+ Ethernet interfaces to incorrectly report packets with more than 2048 bytes
+ in a single USB transfer as having a length of only 2048 bytes.</p>
+ <p>An adversary can exploit this to cause the driver to misinterpret part of the
+ payload of a large packet as a separate packet, and thereby inject packets
+ across security boundaries such as VLANs.</p>
+ <h1>Impact:</h1>
+ <p>An attacker that can send large frames (larger than 2048 bytes in size) to be
+ received by the host (be it VLAN, or non-VLAN tagged packet), can inject
+ arbitrary packets to be received and processed by the host. This includes
+ spoofing packets from other hosts, or injecting packets to other VLANs than
+ the host is on.</p>
