This double-free vulnerability enables an unauthenticated attacker to execute arbitrary code on a vulnerable system remotely. The vulnerability stems from improper memory management within the IKE service. Successful exploitation could lead to complete system compromise, making it a high-priority concern for defenders. Microsoft has assigned a CVSS v3.1 score of 9.8 to this vulnerability. This issue was reported to Microsoft and assigned CVE-2026-33824. The affected systems are those running the Windows IKE Extension without the necessary security update.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn unauthenticated attacker sends a specially crafted IKE packet to the target system.\u003c/li\u003e\n\u003cli\u003eThe Windows IKE Extension processes the malicious IKE packet.\u003c/li\u003e\n\u003cli\u003eDue to a flaw in memory management, the IKE Extension attempts to free the same memory location twice (double-free).\u003c/li\u003e\n\u003cli\u003eThe double-free condition corrupts the heap memory.\u003c/li\u003e\n\u003cli\u003eThe attacker leverages the heap corruption to overwrite critical data structures.\u003c/li\u003e\n\u003cli\u003eThe attacker gains control of program execution flow.\u003c/li\u003e\n\u003cli\u003eThe attacker injects and executes arbitrary code within the context of the IKE service.\u003c/li\u003e\n\u003cli\u003eThe attacker achieves remote code execution, potentially leading to complete system compromise.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-33824 allows a remote, unauthenticated attacker to execute arbitrary code on a vulnerable Windows system.
