How the CVE Works
CVE-2025-47112 is an out-of-bounds (OOB) read vulnerability in Adobe Acrobat Reader affecting versions 24.001.30235, 20.005.30763, 25.001.20521, and earlier. The flaw occurs when parsing a malicious PDF file, causing the application to read memory outside the intended buffer. This can expose sensitive data, including memory addresses, allowing attackers to bypass Address Space Layout Randomization (ASLR). Exploitation requires user interaction—opening a specially crafted PDF—but successful attacks could lead to information disclosure or further exploitation.
