Exploitability
| CWE ID | Description |
|---|---|
| CWE-189 | |
| CWE-190 | The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-9688 is an integer overflow vulnerability in Mupen64Plus (up to version 2.6.0), specifically in the function write_is_viewer in the source file is_viewer.c. This overflow occurs when an integer calculation wraps around unexpectedly, leading to a buffer overflow condition. An attacker can exploit this by injecting malicious code into a game's ROM package, which allows them to escape the emulator sandbox and execute arbitrary code on the host machine. [1, 2]
How can this vulnerability impact me? :
This vulnerability can impact you by compromising the confidentiality, integrity, and availability of your system. Exploiting the integer overflow can allow an attacker to execute arbitrary code on your host machine remotely, potentially leading to unauthorized access, data manipulation, or system disruption. Although the attack requires user interaction and is difficult to exploit, a proof-of-concept is publicly available, increasing the risk. [1, 2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
There are no specific detection commands or network/system detection methods provided for this vulnerability. Detection would likely require analyzing the Mupen64Plus emulator version and monitoring for exploitation attempts involving crafted game ROM packages targeting the write_is_viewer function, but no explicit commands or tools are mentioned.
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include considering replacing the affected Mupen64Plus component with an alternative product, as no official vendor response or patches are available. Since the vulnerability requires user interaction and is difficult to exploit, limiting exposure by avoiding untrusted ROM packages and monitoring for suspicious activity is advisable. [2]
