Linux Distros Unpatched Vulnerability : CVE-2026-75596

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Netty is an asynchronous, event-driven network application framework. Prior to 4.1.137.Final and 4.2.17.Final, the default io.netty.handler.ssl.SniHandler...

CVE-2026-75596

In Netty versions before 4.1.137.Final and 4.2.17.Final, the default SniHandler constructors trigger quadratic CPU work in SslClientHelloHandler#decode by recopying the entire handshake buffer for every additional TLS record. An unauthenticated remote attacker can fragment a large ClientHello int...

Name of the Vulnerable Software and Affected Versions Netty versions prior to 4.1.137.Final Netty versions prior to 4.2.17.Final Description An unauthenticated remote peer can cause quadratic CPU work on the event loop by advertising a large ClientHello and delivering its body in thousands of tin...

Netty: SNI handler pre-allocates up to 16 MiB from nine attacker bytes

SslClientHelloHandler.decode reads the 24-bit TLS handshake length and, when the ClientHello does not fit in the first record, eagerly allocates ctx.alloc.bufferhandshakeLength line 161. The guard at line 140 is handshakeLength maxClientHelloLength && maxClientHelloLength != 0, and the...
