{"id":"OESA-2026-4657","summary":"docker security update","details":"Docker is an open source project to build, ship and run any application as a lightweight container.\r\n\r\nSecurity Fix(es):\n\nDocker 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. Because the transport re-dials the hostname rather than the CIDR-matching address, a DNS answer set of one loopback IP plus a non-loopback attacker IP disables certificate verification and enables HTTP fallback for the registry connection.(CVE-2026-92543)","modified":"2026-10-29T09:15:41.801226863Z","published":"2026-10-29T09:04:08Z","upstream":["CVE-2026-92543"],"database_specific":{"severity":"High"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-4657"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92543"}],"affected":[{"package":{"name":"docker","ecosystem":"openEuler:22.03-LTS-SP4","purl":"pkg:rpm/openEuler/docker&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"engine-18.09.0-355.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["docker-engine-18.09.0-355.oe2203sp4.aarch64.rpm","docker-engine-debuginfo-18.09.0-355.oe2203sp4.aarch64.rpm","docker-engine-debugsource-18.09.0-355.oe2203sp4.aarch64.rpm"],"src":["docker-engine-18.09.0-355.oe2203sp4.src.rpm"],"x86_64":["docker-engine-18.09.0-355.oe2203sp4.x86_64.rpm","docker-engine-debuginfo-18.09.0-355.oe2203sp4.x86_64.rpm","docker-engine-debugsource-18.09.0-355.oe2203sp4.x86_64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-4657.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
