For an IPv4 mapping it writes only the 4-byte .ip\nmember and the loop runs a single 32-bit iteration, but it then copies\nthe whole 16-byte union into range->min_addr and range->max_addr, so the\nupper 12 bytes reach nf_nat_setup_info() uninitialised.\n\nKMSAN reports an uninit-value in nf_nat_setup_info() reached from\nnft_nat_eval(). The IPv6 path fills all 16 bytes and is not affected.\n\nZero-initialise new_addr.\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":[]}
