The MediaTek Product Security Bulletin contains details of security vulnerabilities affecting certain MediaTek chipsets. Device OEMs have been notified of all the issues and the corresponding security patches for at least two months before publication. We take the security of our chipsets and our customers' products very seriously. At this time, we are not aware of any active exploitation of these vulnerabilities in the wild.
The severity of the identified vulnerabilities was conducted based on the Common Vulnerability Scoring System version 3.1 (CVSS v3.1).

Summary
| Severity | CVEs |
|---|---|
| High | CVE-2025-20696 |
| Medium | CVE-2025-20697, CVE-2025-20698 |
Details
| CVE | CVE-2025-20696 |
|---|---|
| Title | Out-of-bounds write in DA |
| Severity | High |
| CWE | CWE-787 Out-of-bounds Write |
| Description | In DA, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege, if an attacker has physical access to the device, with no additional execution privileges needed. User interaction is needed for exploitation. |
| Affected Chipsets | MT6739, MT6761, MT6765, MT6768, MT6781, MT6789, MT6813, MT6833, MT6835, MT6853, MT6855, MT6877, MT6878, MT6879, MT6883, MT6885, MT6886, MT6889, MT6893, MT6895, MT6897, MT6899, MT6983, MT6985, MT6989, MT6990, MT6991, MT8188, MT8196, MT8370, MT8390, MT8676 |
| Affected Software Versions | Android 13.0, 14.0, 15.0 / openWRT 21.02, 23.05 / Yocto 4.0 / RDK-B 24Q1 / Zephyr 3.7.0 |

| CVE | CVE-2025-20697 |
|---|---|
| Title | Out-of-bounds write in Power HAL |
| Severity | Medium |
| CWE | CWE-787 Out-of-bounds Write |
| Description | In Power HAL, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. |
| Affected Chipsets | MT2718, MT6761, MT6765, MT6768, MT6853, MT6855, MT6877, MT6878, MT6879, MT6883, MT6885, MT6889, MT6893, MT6897, MT6989, MT6991, MT8186, MT8196, MT8391, MT8678, MT8775, MT8786, MT8788E, MT8792, MT8796, MT8873, MT8883, MT8893 |
| Affected Software Versions | Android 14.0, 15.0 |
