{"id":"AZL-99273","summary":"CVE-2026-78662 affecting package libcontainers-common 20240213-3","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":"2026-09-08T05:27:28Z","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":"libcontainers-common","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/libcontainers-common"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"20240213-3"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-99273.json"}}],"schema_version":"1.9.0"}
