{"id":"AZL-99207","summary":"CVE-2026-78662 affecting package docker-compose 2.27.0-13","details":"Previously, a channel registered in the mux's chanList is not usable until it is established. A malicious peer was able flood the channel's incomingRequests, deadlocking the entire connection. Now, we add an atomic established state, set when a channel becomes usable. Until such a time, handlePacket drops every packet other than the open confirmation/failure, without blocking and without tearing down the connection.","modified":"2026-09-09T05:29:25Z","published":"2026-09-02T20:17:37Z","upstream":["CVE-2026-78662"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-78662"}],"affected":[{"package":{"name":"docker-compose","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/docker-compose"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.27.0-13"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-99207.json"}}],"schema_version":"1.9.0"}
