Technical description

Yealink SIP-T33G firmware versions 124.86.x.x prior to 124.87.0.0 contain a race condition vulnerability that allows authenticated attackers to interrupt active diagnostic processes by concurrently deleting output files written to predictable paths under the diagnostic directory. Attackers can trigger a diagnostic operation such as traceroute or ping and simultaneously invoke the file deletion endpoint to terminate the running process, leaving the system in an inconsistent state.

CVE-2026-537155.3 MED

———Envoy Gateway is an open source project for managing Envoy Proxy as a standalone or Kubernetes-based application gateway. Prior to 1.7.4 and 1.8.1, HTTPServer.ServeHTTP in internal/wasm/httpserver.go reads the plain mappingPath2Cache map without synchronization while HTTPServer.Get writes the same map during EnvoyExtensionPolicy translation. An attacker with pod-network access to unauthenticated port 18002 and tenant permission to churn policies with distinct Wasm URLs can flood GET requests until a per-request reader overlaps a writer. Go's concurrent map read and write detection invokes runtime.throw, which the net/http connection recovery cannot catch, terminating the controller process and causing a timing-dependent, cross-tenant control-plane denial of service until Kubernetes restarts the pod. This issue is fixed in versions 1.7.4 and 1.8.1.14h CVE-2026-437837.8 HIG
