CVE-2024-37985
📋 TL;DR
This Windows kernel vulnerability allows attackers to read sensitive kernel memory information. It affects Windows systems where an attacker has local access. The vulnerability could expose system information that might aid further attacks.
💻 Affected Systems
- Windows
📦 What is this software?
Windows 11 22h2 by Microsoft

⚠️ Risk & Real-World Impact
Worst Case
Information disclosure could reveal kernel memory structures, potentially enabling privilege escalation or bypassing security mechanisms in combination with other vulnerabilities.
Likely Case
Local attackers could gather system information that helps them understand kernel layout for more sophisticated attacks.
If Mitigated
With proper access controls and least privilege principles, the impact is limited to information disclosure without direct system compromise.
🎯 Exploit Status
Requires local access and kernel-level exploitation knowledge. No public exploits known at this time.
