The mask 0x0f allows values 0-15, but\nthe array size of usb_if->dev[] is only 2. Values 2-15 cause heap\nout-of-bounds read, eventually causing kernel panic in the IRQ context.\n\nAdd bounds checking for ctrl_idx before the array access in both\npcan_usb_pro_handle_canmsg() and pcan_usb_pro_handle_error().","published":"2026-08-15T13:17:50.000Z","lastModified":"2026-08-19T17:21:03.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00177,"percentile":0.07147,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
