MediaTek Chipsets Display Component Privilege Escalation Vulnerability via Use-After-Free

Vulnerability

A vulnerability allowing local privilege escalation has been identified in the display component of certain MediaTek chipsets. This issue arises from a use-after-free condition, which can lead to memory corruption. The vulnerability affects chipsets including MT6739, MT6761, MT6765, MT6768, MT6781, MT6789, MT6833, MT6835, MT6853, MT6855, MT6877, MT6878, MT6879, MT6883, MT6885, MT6886, MT6889, MT6893, MT6895, MT6897, MT6899, MT6983, MT6985, MT6989, MT6991, MT8186, MT8188, MT8196, MT8367, MT8791T, MT8792, MT8793, MT8796, MT8873, MT8883, and MT8893. Exploitation of this vulnerability does not require user interaction, but it necessitates that the attacker has already obtained system privileges.

Impact

Exploitation of this vulnerability could lead to unauthorized privilege escalation, allowing a user with system privileges to gain elevated rights or access.
