CVE-2026-75596

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 constructors use the pre-handshake ClientHello aggregation path in handler/src/main/java/io/netty/handler/ssl/SslClientHelloHandler.java at...

CVE-2026-75596 Netty: Fragmented ClientHello records trigger quadratic pre-handshake reassembly in default SNI parsing

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 constructors use the pre-handshake ClientHello aggregation path in handler/src/main/java/io/netty/handler/ssl/SslClientHelloHandler.java at...

CVE-2026-73500

A flaw was found in etcd, a distributed key-value store. A remote attacker can exploit this by opening numerous TCP connections to an etcd TLS listener without completing the TLS handshake. This action causes the tlsListener.acceptLoop to spawn an unbounded number of goroutines, which consume...

PT-2026-78718

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...

GO-2026-6107 Unbounded TLS handshake goroutines in go.etcd.io/etcd/client/pkg/v3

In go.etcd.io/etcd/client/pkg/v3 before 3.5.33, 3.6.14, and 3.7.1, TLS handshakes on listeners created by NewTLSListener do not enforce a handshake deadline. An unauthenticated network attacker who connects to an etcd TLS listener without sending a ClientHello causes a goroutine and a tracking ma...

CVE-2026-72222

A flaw was found in the Linux kernel's sunrpc component, which affects TLS-enabled Network File System NFS servers. A race condition exists during the asynchronous TLS handshake process. A remote attacker could exploit this by closing a connection at a specific time, leading to memory corruption...

CVE-2026-72221

A flaw was found in the kernel. A race condition exists in the sunrpc component during the Transport Layer Security TLS handshake cancellation process. This can lead to the corruption of an internal data structure, potentially causing system instability or a denial of service. Additionally, it ma...

BIT-ETCD-2026-73500 etcd: `tlsListener.acceptLoop` spawns unbounded handshake goroutines with no deadline

etcd is a distributed key-value store for the data of a distributed system. Prior to versions 3.5.33, 3.6.14, and 3.7.1, a network attacker who can reach an etcd TLS listener can open many TCP connections and never send a ClientHello. In client/pkg/transport/listenertls.go, each connection handle...

BIT-MONGODB-2026-13070 Improper Validation of OCSP Response During Outbound TLS Handshake Leading to Process Termination

A MongoDB server initiating an outbound TLS connection may terminate abnormally when processing a malformed OCSP response from a remote peer during the TLS handshake. OCSP stapling validation is enabled by default for outgoing TLS connections. Affected scenarios require the remote peer to hold a...
