CVE-2026-45386

In Q2 2026, a significant increase in registered vulnerabilities was observed, driven by AI-assisted discovery tools. Multiple critical vulnerabilities were exploited in both Windows and Linux systems, including local privilege escalation flaws in the Linux kernel's caching subsystem (e.g., Dirty Frag family) and newly disclosed Windows Defender and BitLocker bypass vulnerabilities. Exploitation of AI/LLM platforms such as OpenClaw, Dify, and Open WebUI surged, with vulnerabilities enabling session compromise, unauthorized access, and message manipulation. APT groups increasingly targeted newly published and zero-day vulnerabilities, using C2 frameworks like Sliver and Metasploit for post-exploitation. The report highlights growing risks from insecure AI tooling and the need for enhanced access controls and real-time monitoring.
