MediaTek Chipsets Privilege Escalation Vulnerability in PDA Component

A use-after-free vulnerability has been identified in the PDA component of certain MediaTek chipsets, including MT6899, MT6991, and MT8793. This vulnerability could lead to local privilege escalation, but requires that the attacker already has system privileges. The issue arises from improper memory management, allowing for potential exploitation without user interaction.

Impact

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