CVE-2026-33824: Remote Code Execution in Windows IKEv2
A double-free vulnerability in Windows IKEv2 service allows an unauthenticated remote attacker to crash the IKEEXT service or achieve arbitrary code execution by sending crafted Internet Key Exchange packets. The flaw occurs during fragment reassembly when a Security Realm Vendor ID payload causes improper pointer ownership handling in memory, leading to the same heap allocation being freed twice. Microsoft's WARP and MORSE team discovered this vulnerability, which has been patched.
Why it matters: Unauthenticated remote code execution on Windows systems via VPN infrastructure warrants immediate patching if systems are exposed to untrusted networks.

CVE-2026-33824: Remote Code Execution in Windows IKEv2
Researchers disclosed a double‑free flaw in the Windows Internet Key Exchange version 2 (IKEv2) service that could be exploited remotely. The vulnerability permits an unauthenticated attacker to crash the IKEEXT service or achieve arbitrary code execution by sending specially crafted IKEv2 fragments. Microsoft has released a patch addressing the issue in all supported Windows versions.
Why it matters: Windows administrators should apply the Microsoft patch to prevent unauthenticated remote code execution or denial‑of‑service on systems running the IKEv2 service.
