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].","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/29d1d35ad5ad379a904263ea1cd4ba1d71cd965f","tags":[]},{"url":"https://git.kernel.org/stable/c/96d8b26be5bc451188acdcee055948da45adbde0","tags":[]},{"url":"https://git.kernel.org/stable/c/eb7b84af0ec5c71b4920e999611b466b3784496c","tags":[]},{"url":"https://git.kernel.org/stable/c/faba9fdde480356f4a1d3b1a5713b7b354858a1c","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
