CVE-2026-16463: CWE-122 Heap-based Buffer Overflow in Autodesk AutoCAD
A maliciously crafted DXF file, when parsed through Autodesk AutoCAD, can force a Heap-Based Overflow vulnerability. A malicious actor can leverage this vulnerability to cause a crash, read sensitive data, or execute arbitrary code in the context of the current process.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-16463) involves a heap-based buffer overflow triggered by processing a specially crafted DXF file in Autodesk AutoCAD. Successful exploitation can result in a crash, sensitive data leakage, or arbitrary code execution with the privileges of the AutoCAD process. The flaw affects versions 2026.0.0 and 2027.0.0. The CVSS 3.1 vector indicates it requires local access with low attack complexity, no privileges, and user interaction, impacting confidentiality, integrity, and availability. No vendor advisory or patch is currently available, and no active exploitation has been reported.
Potential Impact
An attacker who can supply a malicious DXF file to AutoCAD can cause a heap-based buffer overflow leading to potential application crashes, unauthorized disclosure of sensitive information, or execution of arbitrary code within the AutoCAD process context. This could compromise the confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid opening untrusted DXF files and restrict access to AutoCAD to trusted users only.
