Dec 2025: Microsoft Excel Remote Code Execution Vulnerability
CVE-2025-62560 Published on December 9, 2025
Microsoft Excel Remote Code Execution Vulnerability
Untrusted pointer dereference in Microsoft Office Excel allows an unauthorized attacker to execute code locally.
Weakness Types
Untrusted Pointer Dereference
The program obtains a value from an untrusted source, converts this value to a pointer, and dereferences the resulting pointer.
Buffer Over-read
The software reads from a buffer using buffer access mechanisms such as indexes or pointers that reference memory locations after the targeted buffer. This typically occurs when the pointer or its index is incremented to a position beyond the bounds of the buffer or when pointer arithmetic results in a position outside of the valid memory location to name a few. This may result in exposure of sensitive information or possibly a crash.
