Direct-Memory Resource Leak

RedisArrayAggregator is vulnerable to a direct-memory resource leak. The vulnerability is due to unreleased pooled direct-memory buffers when a Redis pipeline connection closes before a RESP array aggregation completes, which allows an attacker to repeatedly trigger connection churn and exhaust t...

CVE-2026-50011 Netty has unbounded pre-allocation in RedisArrayAggregator from RESP array length

Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final, RedisArrayAggregator pre-allocates ArrayList with initial capacity equal to the RESP array element count declared in an array header. That count is taken fro...

CVE-2026-50011

Netty CVE-2026-50011 affects RedisArrayAggregator in Netty (prior to 4.1.135.Final and 4.2.15.Final). A RESP header can claim a large initial ArrayList capacity, taken from the wire before child messages exist, enabling unbounded pre-allocation. This can cause memory consumption issues. The issue...

Netty: Memory Exhaustion in RedisArrayAggregator due to Deeply Nested Arrays

Summary An attacker can cause DoS by sending a crafted Redis payload with deeply nested arrays. This forces the server to allocate a massive number of state objects and collections, leading to memory exhaustion and an OutOfMemoryError. Details io.netty.handler.codec.redis.RedisArrayAggregator...
