CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability was found in MediaTek MT6781, MT6789, MT6835, MT6855, MT6878, MT6879, MT6886, MT6895, MT6897, MT6983, MT6985, MT6989, MT8370 and MT8390. It has been classified as problematic. This affects an unknown code block of the component Da. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as 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 can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In da, there is a possible out of bounds read due to an integer overflow. This could lead to local information disclosure, if an attacker has physical access to the device, with no additional execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS09291064; Issue ID: MSV-2046.

The advisory is shared at corp.mediatek.com. This vulnerability is uniquely identified as CVE-2025-20653 since 11/01/2024. The exploitability is told to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available.
