**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** An attacker who successfully exploited this vulnerability could bypass the Windows Lock Screen security feature.
**Does this vulnerability affect all versions of TLS?** No. Only those devices running TLS 1.3 are affected. For more information on supported TLS implementations please visit: https://learn.microsoft.com/en-us/windows/win32/secauthn/protocols-in-tls-ssl--schannel-ssp-

**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 take additional actions prior to exploitation to prepare the target environment.
**How could an attacker exploit this vulnerability?** An authenticated attacker could leverage a specially crafted RPC call to the DHCP service to exploit this 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 gather information specific to the environment of the targeted component.
**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** The attacker must inject themselves into the logical network path between the target and the resource requested by the victim to read or modify network communications. This is called a man-in-the-middle (MITM) attack.
**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.
**How could an attacker exploit this vulnerability?** In a network-based attack an attacker would need to have the privileges to query the Domain Name Service (DNS). If the timing of DNS queries is perfect, the attacker could execute code remotely on the target server.
**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.
