CVE-2025-68343

CVE-2025-68343 in the Linux kernel affects the can: gs_usb driver (gs_usb_receive_bulk_callback). The vulnerability arises from not validating the actual_length before accessing the gs_host_frame header, risking dereference of an incomplete header. The fix uses struct_group to describe the header...
