MediaTek MT8797 Meta buffer 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 classified as critical was found in MediaTek MT6761, MT6765, MT6768, MT6779, MT6781, MT6785, MT6789, MT6833, MT6835, MT6853, MT6855, MT6873, MT6877, MT6879, MT6883, MT6885, MT6886, MT6889, MT6893, MT6895, MT6983, MT6985, MT8167, MT8167S, MT8168, MT8173, MT8175, MT8185, MT8188, MT8188T, MT8195, MT8321, MT8362A, MT8365, MT8390, MT8395, MT8666, MT8675, MT8766, MT8768, MT8786, MT8788, MT8789 and MT8797 (Chip Software). Affected by this vulnerability is an unknown function of the component Meta. The manipulation with an unknown input leads to a buffer overflow vulnerability. The CWE definition for the vulnerability is CWE-120. The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

In meta, there is a possible classic buffer overflow due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS08000473; Issue ID: ALPS08000473.

The weakness was presented 12/04/2023 as ALPS08000473. The advisory is shared at corp.mediatek.com. This vulnerability is known as CVE-2023-32859 since 05/16/2023. Neither technical details nor an exploit are publicly available.
