About this tag
CVE-2025-68342 is a Linux kernel vulnerability in the gs_usb CAN-over-USB driver. It involves missing length checks that could allow out-of-bounds reads and denial-of-service conditions when handling USB payloads from untrusted CAN devices or during USB passthrough. The fix adds explicit length validation to ensure the kernel only reads data within received USB buffers. This tag covers discussions about the vulnerability, its patch, and implications for systems using USB CAN interfaces.

  1. Linux Kernel gs_usb CAN Patch Adds Length Checks Fixing CVE-2025-68342

    A newly disclosed Linux kernel vulnerability, tracked as CVE‑2025‑68342, plugs a long‑standing robustness hole in the gs_usb CAN‑over‑USB driver by adding explicit length checks to prevent the kernel from reading past received USB payloads. The fix introduces a helper to compute the minimum...
