GHSA-6XR9-PVGC-M3PC

Vulnerability from github – Published: 2025-02-27 03:34 – Updated: 2025-03-05 21:32

Details

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.

Severity ?

7.1 (High)
