About this video

A survey of remote code execution warnings across seven groups of systems in 2026, from Windows and Android to RouterOS and ChromeOS. It separates published severity from confirmed exploitation, because real risk depends on version, configuration and attack conditions.

🚨 RCE 2026: seven groups of systems face severe remote code execution vulnerabilities, from Windows and Android to RouterOS and ChromeOS. The warning list covers Windows, Android, Linux Server, FreeBSD, Apple, RouterOS and ChromeOS.

RCE (Remote Code Execution) is a vulnerability that lets an attacker execute code remotely on an affected system.

🔍 Notable findings:

  • Windows MSMQ: CVE-2026-100202 reaches CVSS 9.8.
  • Android: several Critical RCE vulnerabilities require no user interaction.
  • PHP2Shell: two severe RCE vulnerabilities were patched urgently on 21 October 2026.
  • RouterOS: the MikroTrick attack chain has evidence of real-world exploitation.
  • FreeBSD, Apple and ChromeOS: notable risks related to memory, file handling and the sandbox.

⚠️ Not every vulnerability has been successfully exploited. The level of risk depends on the version, configuration and attack conditions.
