✅ Remediation
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: For Redis instances where TLS is enabled, consider disabling TLS if it is not strictly required. Alternatively, restrict network access to the Redis server to trusted clients only, using firewall rules or network access controls, to prevent unauthenticated remote attackers from reaching the vulnerable service. If TLS is enabled, a restart of the Redis service may be required for changes to take effect.
