CVE-2025-2532
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code by tricking users into opening malicious USDC files in Luxion KeyShot. Attackers can gain full control of the affected system through a use-after-free memory corruption flaw. All users running vulnerable versions of KeyShot are affected.

📦 What is this software?
Keyshot by Luxion
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining the same privileges as the KeyShot user, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Local privilege escalation leading to data exfiltration, malware installation, or persistence mechanisms being established on the compromised system.
If Mitigated
Limited impact due to sandboxing or restricted user privileges, potentially resulting in application crash or denial of service.
🎯 Exploit Status
Exploitation requires user interaction (opening malicious file). The use-after-free condition requires precise memory manipulation to achieve reliable code execution.
