A remote attacker can exploit this vulnerability by sending specially crafted nested Redis (RESP) array headers. This can cause the `RedisArrayAggregator` to eagerly preallocate a large amount of heap memory, leading to heap memory exhaustion and a Denial of Service (DoS) for applications using `RedisDecoder` with `RedisArrayAggregator` on untrusted traffic.","state":0,"publishedAt":"2026-09-18T10:53:54.295+00:00","modifiedAt":"2026-09-25T08:29:02.541+00:00","affected":[{"ecosystem":"https://access.redhat.com/downloads/content/package-browser/","name":"netty-codec-redis","ranges":[],"versions":[],"rawVersionEvidence":"{\n
