GHSA-6ghj-frrj-jjj3: Netty has Unbounded Direct Memory Consumption in its RedisDecoder

Netty's RedisDecoder (a tool that reads Redis protocol messages) has a vulnerability where an attacker can send malformed Redis messages without proper line endings (`\r\n`) across multiple connections, causing the decoder to buffer data indefinitely and exhaust the server's direct memory pool (memory reserved for direct I/O operations), resulting in a DoS (denial of service) attack that prevents legitimate users from connecting.
