CVE-2026-65654 temporalio/ringpop-go fails to enforce configured label limits on inbound membership gossip

github.com/temporalio/ringpop-go enforces configured LabelOptions limits when an application changes the local node's labels, but affected versions do not apply those limits to label maps received in SWIM membership changes. A network peer that can reach a live Ringpop TChannel listener can...

crypto/x509: crypto/tls: golang: Go: Denial of Service vulnerability in certificate chain building

A flaw was found in the Go standard library packages crypto/x509 and crypto/tls. During the process of building a certificate chain, an attacker can provide a large number of intermediate certificates. This excessive input is not properly limited, leading to an uncontrolled amount of work being...

net/http: golang: Go net/http: Unencrypted HTTP/2 connections vulnerable to Denial of Service

A flaw was found in the net/http component of the Go standard library. When a server is configured to support unencrypted HTTP/2, it reads initial bytes from new connections to detect the HTTP/2 client preface. However, the ReadHeaderTimeout is not correctly applied during this process. This...

golang: internal/syscall/unix: Root.Chmod can follow symlinks out of the root

A flaw was found in the internal/syscall/unix package in the Go standard library. If the target of the Root.Chmod function is replaced with a symbolic link during execution, specifically after Root.Chmod checks the target but before acting, the chmod operation will be performed on the file the...
