A nonzero command shorter than CMD_HEADER_LEN can still be dispatched, and the wait path copies a matching command into a fixed caller-owned struct kvaser_cmd using the device-provided length. Reject nonzero commands that do not contain the fixed header or that extend beyond the current USB buffer item. In the wait path, also reject a matching command that exceeds the destination before copying it. Join the discussion | GCVE Database | 08/17/2026, 00:00:00 UTC Added: 08/17/2026, 22:36:46 UTC |
