Sep 2025: Microsoft Excel Information Disclosure Vulnerability
CVE-2025-54901 Published on September 9, 2025
Microsoft Excel Information Disclosure Vulnerability
Buffer over-read in Microsoft Office Excel allows an unauthorized attacker to disclose information locally.
Weakness Type
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.
