MediaTek MT8797 thermal memory corruption

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 classified as critical has been found in MediaTek MT6580, MT6739, MT6761, MT6762, MT6765, MT6768, MT6769, MT6771, MT6779, MT6781, MT6785, MT6789, MT6833, MT6853, MT6855, MT6873, MT6879, MT6883, MT6885, MT6889, MT6891, MT6893, MT6895, MT6983, MT8167, MT8167S, MT8168, MT8175, MT8321, MT8362A, MT8365, MT8385, MT8765, MT8766, MT8768, MT8781, MT8786, MT8788, MT8789, MT8791T and MT8797 (Chip Software). This affects an unknown part of the component thermal. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In thermal, there is a possible memory corruption due to an uncaught exception. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07494460; Issue ID: ALPS07494460.

The weakness was released 03/08/2023 as ALPS07494460. The advisory is shared at corp.mediatek.com. This vulnerability is uniquely identified as CVE-2023-20628 since 10/28/2022. Neither technical details nor an exploit are publicly available.

Applying the patch ALPS07494460 is able to eliminate this problem.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2023-24807). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
