Successful exploitation could result in elevation of privileges, allowing the attacker to gain higher-level permissions on the affected system. Microsoft has released an official patch to remediate this vulnerability.

An authorized local attacker can exploit this integer overflow vulnerability to elevate their privileges on the affected Windows 11 system. This could lead to unauthorized actions with higher privileges, potentially compromising system integrity, confidentiality, and availability.
