{"id":"AZL-113543","summary":"CVE-2026-112320 affecting package krb5 1.21.3-6","details":"The GSS-RPC transport layer in MIT Kerberos 5 (aka krb5) 1.4 and later does not release the previous authentication context when a client switches from an RPCSEC_GSS or AUTH_GSSAPI flavor to a non-GSS flavor on the same TCP connection. This allows remote attackers to cause a denial of service (memory exhaustion in kadmind) by repeatedly establishing and abandoning GSS authentication contexts.","modified":"2026-11-14T05:30:17Z","published":"2026-11-09T19:16:40Z","upstream":["CVE-2026-112320"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112320"}],"affected":[{"package":{"name":"krb5","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/krb5"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.21.3-6"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-113543.json"}}],"schema_version":"1.9.2"}
