CVE-2026-48006: 
Java Analyse et atténuation des vulnérabilités

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 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.
