1. Critical OS & Kernel Vulnerabilities (Linux, Windows, Chrome):
02 May 2026
• Google Chrome navigation‑component bug (EUVD‑2026‑28021) – pre‑v148.0.7778.96 allowed a compromised renderer to bypass site‑isolation via a crafted HTML page (medium‑severity, “Chromium security severity: Medium”).
• Affects any Chrome‑based browsers used by developers or internal tools (Chrome, Edge, Chromium). Bypass of site‑isolation can lead to cross‑origin data leakage.

06 May 2026
• Palo Alto Networks PAN‑OS User‑ID Authentication Portal buffer overflow (CVE‑2026‑0300) – remote unauthenticated RCE with full root privileges on PA‑Series & VM‑Series firewalls.
• Our Azure‑based perimeter firewalls (if Palo Alto) could be fully compromised, allowing lateral movement into on‑prem or cloud workloads.

06 May 2026
• Linux kernel “perf/x86” privilege‑escalation (CVE‑2026‑31782, CVSS 7.8) – local exploit in the perf subsystem.
• Affects all Linux hosts (including our container base images) that ship the vulnerable kernel; could be leveraged after initial foothold to gain root.
