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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
