MediaTek MT8910 Audio HAL path traversal

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.

Detailsinfo

A vulnerability was found in MediaTek MT2718, MT6769, MT6781, MT6789, MT6833, MT6835, MT6853, MT6855, MT6858, MT6877, MT6878, MT6881, MT6886, MT6893, MT6895, MT6897, MT6899, MT6989, MT6991, MT6993, MT8126, MT8168, MT8171, MT8186, MT8188, MT8189, MT8195, MT8196, MT8321, MT8365, MT8367, MT8385, MT8390, MT8391, MT8668, MT8676, MT8678, MT8696, MT8755, MT8766, MT8768, MT8771, MT8775, MT8781, MT8786, MT8788E, MT8791T, MT8792, MT8793, MT8796, MT8797, MT8798, MT8799, MT8873, MT8883, MT8893 and MT8910. It has been classified as problematic. This affects some unknown processing of the component Audio HAL. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-35. The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '.../...//' (doubled triple dot slash) sequences that can resolve to a location that is outside of that directory. This is going to have an impact on confidentiality. The summary by CVE is:

In Audio HAL, there is a possible information disclosure due to improper input validation. This could lead to local information disclosure if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS11087533; Issue ID: MSV-8245.

The advisory is shared at mediatek.com. This vulnerability is uniquely identified as CVE-2026-20513 since 11/03/2025. The exploitability is told to be easy. An attack has to be approached locally. Additional levels of successful authentication are needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1006 for this issue.

Applying the patch ALPS11087533 is able to eliminate this problem.
