The policy only bounds\nthe attribute from above (NLA_BINARY .len is a maximum) and the op sets\nGENL_DONT_VALIDATE_STRICT, so a short or zero-length attribute is\naccepted and the loop reads past the payload.\n\nRequire the exact length in the policy, so a malformed attribute is\nrejected before the handler runs.","categories":["Operating
