CVE-2026-44375: Memory Allocation with Excessive Size Value

Nerdbank.MessagePack is a NativeAOT-compatible MessagePack serialization library. Prior to 1.1.62, Nerdbank.MessagePack contains an uncontrolled stack allocation vulnerability in DateTime decoding. A malicious MessagePack payload can declare an oversized timestamp extension length, causing the...

CVE-2026-44248

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, the MQTT 5 header Properties section is parsed and buffered before any message size limit is applied. Specifically, in MqttDecoder, the decodeVariableHeader method is called before the...

DEBIAN-CVE-2026-42582

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final, when decoding header blocks, the non-Huffman branch of io.netty.handler.codec.http3.QpackDecoderdecodeHuffmanEncodedLiteral may execute new bytelength for a string literal before verifying that length byt...

CVE-2026-42579

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, Netty's DNS codec does not enforce RFC 1035 domain name constraints during either encoding or decoding. This creates a bidirectional attack surface: malicious DNS responses can exploit t...

CVE-2026-44289

CVE-2026-44289 affects protobufjs. Before versions 7.5.6 and 8.0.2, decoding nested protobuf data could recurse without a depth limit, affecting both skipping unknown group fields and generated decoding of nested message fields. A crafted binary payload could exhaust the JavaScript call stack, ca...

CVE-2026-44289 protobufjs: Denial of service through unbounded protobuf recursion

protobufjs compiles protobuf definitions into JavaScript JS functions. Prior to 7.5.6 and 8.0.2, protobufjs could recurse without a depth limit while decoding nested protobuf data. This affected both skipping unknown group fields and generated decoding of nested message fields. A crafted protobuf...
