The variable 'j' tracks the\ncompacted index into the destination data buffer, whereas 'i' iterates\nover all elements in bcm_sysport_gstrings_stats.\n\nBecause the buffer allocated by ethtool is sized only according to\nbcm_sysport_get_sset_count(), storing values at data[i] instead of\ndata[j] writes past the allocated array bounds, leading to memory\ncorruption.\n\nFix this by writing to data[j] instead of data[i].\n\n## Affected\n\n- `Linux >= 10377ba7673d19e28d92846955d51f49acd25c35 < 29d1d35ad5ad379a904263ea1cd4ba1d71cd965f`\n- `Linux >= 10377ba7673d19e28d92846955d51f49acd25c35 < 96d8b26be5bc451188acdcee055948da45adbde0`\n- `Linux >= 10377ba7673d19e28d92846955d51f49acd25c35 < faba9fdde480356f4a1d3b1a5713b7b354858a1c`\n- `Linux >= 10377ba7673d19e28d92846955d51f49acd25c35 < eb7b84af0ec5c71b4920e999611b466b3784496c`\n- `Linux 4.14`\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":[]}
