**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

**What type of information could be disclosed by this vulnerability?** An attacker who successfully exploited the vulnerability could potentially read User Mode Service Memory.

**What privileges could an attacker gain?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**According to the CVSS metric, the attack vector is local (AV:L).
