CVE-2026-48006 is a memory leak vulnerability in Netty's Redis protocol support, specifically the RedisArrayAggregator handler in netty-codec-redis. In affected versions prior to 4.1.135.Final and 4.2.15.Final, the handler retains child RESP messages in per-handler aggregation state and fails to release them if a Redis pipeline connection is closed before a RESP array aggregate is fully assembled. The vulnerable logic does not implement teardown-path cleanup for retained messages during channel inactivity, handler removal, or exception handling. Because the leaked objects are pooled direct-memory buffer slices backed by Netty's PooledByteBufAllocator, the underlying allocator chunks cannot be returned to the shared JVM direct-memory pool. Repeated premature connection termination during incomplete RESP array aggregation can therefore accumulate unreleased direct memory and lead to process-wide resource exhaustion.

A denial-of-service vulnerability in Netty's RedisArrayAggregator handler that leaks pooled direct-memory buffers when a Redis pipeline connection closes before a RESP array aggregate completes, eventually exhausting the JVM-wide direct-memory pool and causing allocation failures.
