CVE-2025-27162

Code execution via uninitialized AcroForm memory

Published Mar 11, 2025 · Updated Feb 26, 2026

Access of uninitialized memory in Adobe Acrobat Reader DC 25.001.20428 and earlier allows remote attackers to execute code via a crafted file. AcroForm handling accesses memory before it is properly initialized, allowing attacker-controlled content to redirect execution. Acrobat Reader 2020 20.005.30748 and earlier is also affected; the target must open malicious content, and code runs in the current process.
