CVE-2026-92543 Docker Engine insecure-registry fallback via malicious DNS responses

Docker Engine classifies a registry hostname as insecure using an any-match DNS check. loadInsecureRegistries injects 127.0.0.0/8 and ::1/128 as insecure CIDRs by default. isCIDRMatch resolves all of the hostname's addresses and returns true if a single address is in the insecure CIDR list. Becau...
