Frequently Asked Questions
Who can exploit this vulnerability?
An attacker must already be authorized on the affected system and have local access. The issue is an elevation of privilege vulnerability, so it is relevant where lower-privileged local users or processes may be present.
Is remote exploitation or user interaction required?
No. The supplied vector identifies local attack access and no user interaction requirement. It does not indicate that the vulnerability can be exploited remotely.
What impact could successful exploitation have?
Successful exploitation could allow elevation of privileges with high confidentiality, integrity, and availability impact. This could enable an authorized local attacker to access, modify, or disrupt resources beyond their intended permissions.
