Out-of-Bounds Read Vulnerability in Linux Kernel USB Networking Component

CVE-2025-21743

What is CVE-2025-21743?

A vulnerability exists in the USB networking component of the Linux kernel, specifically in the ipheth driver, where improper handling of the datagram index and length could result in an out-of-bounds (OoB) read. This issue arises if the sum of the datagram index and length exceeds the maximum value for a 16-bit unsigned integer. To mitigate the risk, appropriate checks have been implemented ensuring that the datagram index remains within safe limits relative to the actual length of the USB request.
