CVE-2025-24079 is a use-after-free vulnerability in Microsoft Office Word. The flaw arises from improper handling of object lifetime in Word, creating a condition where memory can be reused after it has been freed. An unauthorized attacker who can trigger the vulnerable state may achieve code execution in the context of the affected application. Available reporting identifies the issue as affecting Microsoft Word and classifies it as a remote code execution vulnerability, although the concise vendor-style description specifically states code execution locally.
