MediaTek MT8798 12.0/13.0/Android 11.0 Keyinstall type confusion

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.

It has been rated as problematic. Affected by this issue is some unknown processing of the component Keyinstall. The manipulation with an unknown input leads to a type confusion vulnerability. Using CWE to declare the problem leads to CWE-843. The product allocates or initializes a resource such as a pointer, object, or variable using one type, but it later accesses that resource using a type that is incompatible with the original type. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In keyinstall, there is a possible memory corruption due to type confusion. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS08157918; Issue ID: ALPS08157918.

The weakness was disclosed 11/06/2023 as ALPS08157918. The advisory is available at corp.mediatek.com. This vulnerability is handled as CVE-2023-32835 since 05/16/2023. The technical details are unknown and an exploit is not available.

Applying the patch ALPS08157918 is able to eliminate this problem.
