SCA: security update for io.netty:netty-codec-redis (GHSA-6jv9-x5w9-2ccm)

high Tenable Cloud Security Plugin ID 443085

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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 completes. The
 handler retains child messages in per-handler state (`depths` field) but defines no `channelInactive`,
 `handlerRemoved`, or `exceptionCaught` method to release them when the pipeline tears down. Because the
 leaked buffers are slices of `PooledByteBufAllocator` chunks, they prevent those chunks from being
 returned to the JVM-wide direct-memory pool. Repeated connection churn by any network peer monotonically
 drains this shared pool, eventually causing allocation failures on all Netty channels in the process.
 Versions 4.1.135.Final and 4.2.15.Final patch the issue. (CVE-2026-48006)

Solution

Update the io.netty:netty-codec-redis library and its related packages to version 4.1.135.Final or later.
