{"id":"AZL-96888","summary":"CVE-2026-56684 affecting package valkey for versions less than 8.0.10-1","details":"Valkey is a distributed key-value database. Prior to 7.2.14, 8.0.10, 8.1.9, 9.0.5, and 9.1.1, Valkey's tlsProcessPendingData function iterates pending_list while an authenticated client can trigger CLIENT KILL, causing connTLSClose to delete the iterator's cached next node and producing a use-after-free that can crash the server or potentially allow remote code execution when TLS is enabled. This issue is fixed in versions 7.2.14, 8.0.10, 8.1.9, 9.0.5, and 9.1.1.","modified":"2026-08-30T05:26:50Z","published":"2026-08-18T15:16:55Z","upstream":["CVE-2026-56684"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-56684"}],"affected":[{"package":{"name":"valkey","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/valkey"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.0.10-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-96888.json"}}],"schema_version":"1.9.0"}
