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.\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":[]}
