Summary
valkey vulnerabilities
Details

Madelyn Olson discovered that Valkey incorrectly handled TLS connections under certain conditions. A remote attacker could possibly use this issue to cause Valkey to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2026-56684)

It was discovered that Valkey incorrectly handled certain stream RDB payloads when executing the RESTORE command. An authenticated remote attacker could possibly use this issue to cause Valkey to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2026-63639)

It was discovered that Valkey incorrectly handled cluster slot migration operations. A remote attacker could possibly use this issue to cause Valkey to crash, resulting in a denial of service. This issue was only addressed in Ubuntu 26.04 LTS. (CVE-2026-85522)
