Frequently Asked Questions
1
Can this be exploited remotely or by an unprivileged user?
No. The CVSS vector indicates local access and high privileges are required, so a remote unauthenticated attacker or a standard unprivileged user is not described as able to exploit it.
2
What could a successful exploit affect?
The CVSS vector rates confidentiality, integrity, and availability impacts as high. Its scope is unchanged, meaning the assessed impact remains within the same security authority.
