A USB device can trigger OOB by advertising the maximum\nnumber of properties.\n\nFix by dropping the redundant `+ i`; num_properties is already the correct\nrunning index, as gud_connector_fill_properties() fills the preceding\nslots.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE
