MediaTek MT8883 Modem integer overflow

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 MT2716, MT6813, MT6815, MT6835, MT6858, MT6878, MT6881, MT6897, MT6899, MT6982, MT6986, MT6988, MT6991, MT6993, MT8668, MT8676, MT8678, MT8755, MT8775, MT8792, MT8793, MT8863, MT8873, MT8875 and MT8883. It has been rated as critical. Affected by this issue is an unknown function of the component Modem. The manipulation with an unknown input leads to a integer overflow vulnerability. Using CWE to declare the problem leads to 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. Impacted is availability. CVE summarizes:

In Modem, there is a possible way (for XXX) to XXXXX due to an integer overflow. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01334054 / MOLY01312486; Issue ID: MSV-7920.
