| CVE | Sev | CVSS | KEV | Affected versions | Fixed in | Published | Description |
|---|---|---|---|---|---|---|---|
| CVE-2026-42583 | Hig | 7.5 | < 4.1.133.Final | 4.1.133.Final | May 13, 2026 | Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, Lz4FrameDecoder allocates a ByteBuf of size decompressedLength (up to 32 MB per block) before LZ4 runs. A peer only needs a 21-byte header plus compressedLength payload | |
| CVE-2025-58057 | Hig | 7.5 | < 4.1.125.Final | 4.1.125.Final | Sep 4, 2025 | Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In netty-codec-compression versions 4.1.124.Final and below, and netty-codec versions 4.2.4.Final and below, when supplied with s | |
| CVE-2021-37137 | Hig | 7.5 | >= 4.0.0, < 4.1.68.Final | 4.1.68.Final | Oct 19, 2021 | The Snappy frame decoder function doesn't restrict the chunk length which may lead to excessive memory usage. Beside this it also may buffer reserved skippable chunks until the whole chunk was received which may lead to excessive memory usage as well. This vulnerability can be tr | |
| CVE-2021-37136 | Hig | 7.5 | < 4.1.68.Final | 4.1.68.Final | Oct 19, 2021 | The Bzip2 decompression decoder function doesn't allow setting size restrictions on the decompressed output data (which affects the allocation size used during decompression). All users of Bzip2Decoder are affected. The malicious input can trigger an OOME and so a DoS attack |
