gs usb driver

The gs usb driver tag on WindowsForum covers discussions about the GS_USB CAN driver in the Linux kernel, particularly a security vulnerability (CVE-2025-68343) that could lead to kernel memory corruption. The flaw involved a missing length check in the gs_usb_receive_bulk_callback handler, where the driver assumed a full header was present in USB bulk transfers. This could cause crashes or reliability issues on systems using GS_USB-based CAN devices. Patches were posted to kernel mailing lists in November 2025, and downstream distributions have issued updates at varying cadences. The tag is relevant for users and administrators managing Linux systems with GS_USB CAN hardware, especially those concerned with kernel security and stability.
