How CVE-2025-47111 Works
CVE-2025-47111 is a NULL pointer dereference vulnerability in Adobe Acrobat Reader. When parsing a specially crafted PDF file, the application fails to handle a malformed object reference, causing it to dereference a NULL pointer. This leads to an immediate crash of the application, resulting in denial-of-service. The exploit requires user interaction, as the victim must open the malicious PDF. The vulnerability stems from insufficient validation of object references during PDF parsing, allowing an attacker to trigger the crash by embedding a corrupted object in the file.
