Denial Of Service (DoS)

Netty is vulnerable to Denial of Service DoS. The vulnerability is due to RedisArrayAggregator pre-allocating an ArrayList based on an untrusted RESP array element count from the network, which allows an attacker to trigger excessive memory allocation and exhaust system resources by sending a...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in RedisArrayAggregator. An attacker who sends a small RESP array header declaring a very large element count can force the aggregator to reserve a large ArrayList via the...

CVE-2026-50011

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...

That count is taken fro...

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 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...

CVE-2026-48006 Netty's Lack of Lifecycle Cleanup Leads to Pooled ByteBuf Leak in RedisArrayAggregator

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, the RedisArrayAggregator handler permanently leaks pooled direct-memory buffers when a Redis pipeline connection closes before a RESP array aggregate...

CVE-2026-48006

Summary : CVE-2026-48006 relates to Netty’s RedisArrayAggregator leaking pooled direct-memory buffers when a Redis pipeline connection closes before a RESP array aggregate completes. This occurs prior to Netty versions 4.1.135.Final and 4.2.15.Final . Root cause : The RedisArrayAggregator retains...

Name of the Vulnerable Software and Affected Versions Netty versions prior to 4.1.135.Final Netty versions prior to 4.2.15.Final Description Netty is a network application framework for developing protocol servers and clients. The RedisArrayAggregator pre-allocates an ArrayList with an initial...

CVE-2026-44250

CVE-2026-44250 describes memory exhaustion DoS in Netty’s RedisArrayAggregator. Affected: io.netty:netty-codec-redis in versions prior to 4.1.135.Final and 4.2.15.Final. Root cause: processing of deeply nested Redis arrays from a crafted payload causes unbounded AggregateState/ArrayList allocatio...

Netty's Lack of Lifecycle Cleanup Leads to Pooled ByteBuf Leak in RedisArrayAggregator

Impact The RedisArrayAggregator handler permanently leaks pooled direct-memory buffers when a Redis pipeline connection closes before a RESP array aggregate completes. The handler retains child messages in per-handler state depths field but defines no channelInactive, handlerRemoved, or...

Missing Release of Memory after Effective Lifetime

Overview Affected versions of this package are vulnerable to Missing Release of Memory after Effective Lifetime due to improper cleanup of pooled direct-memory buffers in the RedisArrayAggregator function. An attacker can exhaust the JVM-wide direct-memory pool by repeatedly opening and closing...

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...
