CVE-2025-21743
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.
