Description

In the Linux kernel, the following vulnerability has been resolved:

usbnet: ipheth: fix possible overflow in DPE length check

Originally, it was possible for the DPE length check to overflow if wDatagramIndex + wDatagramLength > U16_MAX. This could lead to an OoB read.

Move the wDatagramIndex term to the other side of the inequality.

An existing condition ensures that wDatagramIndex < urb->actual_length.
