CVE-2025-62473 Published on December 9, 2025

Windows Routing and Remote Access Service (RRAS) Information Disclosure Vulnerability
Buffer over-read in Windows Routing and Remote Access Service (RRAS) allows an unauthorized attacker to disclose information over a network.

Vendor Advisory NVD

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.
