Mediatek Multiple Chipsets Insufficient Input Validation Vulnerability

Published Mar 10, 2020 · updated Jun 16, 2026 · google android

In the ioctl handlers of the Mediatek Command Queue driver, there is a possible out of bounds write due to insufficient input sanitization and missing SELinux restrictions. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-147882143References: M-ALPS04356754

Sources

  • CISA KEVCVE-2020-0069

    Multiple MediaTek chipsets contain an insufficient input validation vulnerability and have missing SELinux restrictions in the Command Queue drivers ioctl handlers. This causes an out-of-bounds write leading to privilege escalation. This vulnerability was observed chained with CVE-2019-2215 and CVE-2020-0041 under exploit chain "AbstractEmu."
