{"id":"AZL-86093","summary":"CVE-2026-23479 affecting package valkey for versions less than 8.0.9-1","details":"Redis is an in-memory data structure store. In redis-server from 7.2.0 until 8.6.3, the unblock client flow does not handle an error return from `processCommandAndResetClient` when re-executing a blocked command. If a blocked client is evicted during this flow, an authenticated attacker can trigger a use-after-free that may lead to remote code execution. This has been patched in version 8.6.3.","modified":"2026-09-04T05:27:10Z","published":"2026-05-05T17:17:02Z","upstream":["CVE-2026-23479"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23479"}],"affected":[{"package":{"name":"valkey","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/valkey"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.0.9-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-86093.json"}}],"schema_version":"1.9.0"}
