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."
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.
