The issue is related to a use-after-free vulnerability in the XFA engine, specifically tied to validation functionality. This could allow for arbitrary code execution if successfully exploited. The vulnerability is also related to memory use after it has been freed, which can be exploited by a remote attacker to execute arbitrary code, potentially related to checking functionality.

The issue is related to a lack of access control in the Windows operating system kernel driver, allowing a local attacker to potentially elevate their privileges using a specially crafted application. This could affect the system, enabling attackers to gain higher privileges.
