RLSA-2026:25219 Important: redis:7 security update

Redis is an advanced key-value store. It is often referred to as a data-structure server since keys can contain strings, hashes, lists, sets, and sorted sets. For performance, Redis works with an in-memory data set. You can persist it either by dumping the data set to disk every once in a while, ...

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...

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.

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...
