HIGH

Linux Kernel 6.5-6.6.77, 6.7-6.12.13, 6.13-6.13.2 - Out-of-bounds Read in USB Networking ipheth Driver

Title source: llm
STIX 2.1

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.
