{"id":"DEBIAN-CVE-2026-23479","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":"2026-08-27T23:05:47.757516148Z","published":"2026-05-05T17:17:02.577Z","upstream":["CVE-2026-23479"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-23479"}],"affected":[{"package":{"name":"redis","ecosystem":"Debian:13","purl":"pkg:deb/debian/redis?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5:8.0.2-3","5:8.0.2-3+deb13u1","5:8.0.2-3+deb13u2","5:8.0.4-1","5:8.0.5-1","5:8.0.6-1","5:8.0.6-2","5:8.4.0-1","5:8.6.1-1","5:8.6.2-1","5:8.6.3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-23479.json"}},{"package":{"name":"redis","ecosystem":"Debian:14","purl":"pkg:deb/debian/redis?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5:8.0.2-3","5:8.0.4-1","5:8.0.5-1","5:8.0.6-1","5:8.0.6-2","5:8.4.0-1","5:8.6.1-1","5:8.6.2-1","5:8.6.3-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-23479.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
