Because ndp_index is compared against\nunsigned bounds, this negative value bypasses sanity checks and leads\nto an out-of-bounds read when calculating the address of the NDP\nblock (ntb_ptr + ndp_index).\n\nFix this by changing ndp_index to unsigned int to ensure consistent\nunsigned comparisons throughout the function.","published":"2026-08-22T16:16:42.000Z","lastModified":"2026-10-14T13:10:00.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00185,"percentile":0.08061,"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.
