The vulnerability allows a local attacker to bypass security restrictions on the target system.The weakness exists due to improper security restrictions when using the large memory pages option. When using this option, the SeLockMemoryPrivilege privilege is added to the current user account using the LsaAddAccountRights function, which allows other applications on the system access to that privilege. A local attacker can execute an application on the system, which can run with SeLockMemoryPrivilege privileges, and bypass access restrictions.
