Windows BitLocker Information Disclosure Vulnerability

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 invest time in repeated exploitation attempts through sending constant or intermittent data.

What type of information could be disclosed by this vulnerability?
The type of information that could be disclosed if an attacker successfully exploited this vulnerability is raw unencrypted disk sector data.

According to the CVSS metrics, successful exploitation of this vulnerability could lead to major loss of confidentiality (C:H) and major loss of integrity (I:H) but have no effect on availability (A:N). What does that mean for this vulnerability?
An attacker who successfully exploited this vulnerability could access specific parts of the storage device and could read or write to portions of the device that are unencrypted. However, this vulnerability would not allow an attacker to deny function of the storage device.

How could an attacker exploit this vulnerability?
An attacker could access unencrypted parts of a BitLocker encrypted storage device if the administrator resizes the OS volume while concurrently provisioning the drive with BitLocker encryption.

According to the CVSS metric, privileges required is high (PR:H). What does that mean for this vulnerability?
Successful exploitation of this vulnerability requires the attacker or targeted user to have specific elevated privileges. As is best practice, regular validation and audits of administrative groups should be conducted.
