Linux KVM escape, Cisco SD-WAN patches, Spectre v2 defenses bypassed

This briefing highlights multiple high‑severity threats requiring urgent action: Zapscape (CVE‑2026‑6) enables KVM guest‑to‑host escapes when nested virtualization is exposed, Cisco released patches for 12 critical SD‑WAN/IOS XE flaws, MIT CSAIL demonstrated an interrupt‑injection Spectre v2 bypass on Intel/AMD, a ClickFix Go‑based macOS infostealer is stealing crypto and credentials, and a Swiss SharePoint breach compromised ~200 accounts; recommended actions prioritize disabling nested virtualization for untrusted guests, deploying vendor patches, and auditing affected services.
