#Windows Kerberos

**How could an attacker exploit this vulnerability?** An unauthenticated attacker could use a specially crafted application to leverage a protocol vulnerability in Windows Kerberos to perform a denial of service attack against the target.

**Are there any additional steps that I need to follow to be protected from this vulnerability?** The changes to address this vulnerability updated Virtual Secure Mode components. The policy described in Guidance for blocking rollback of Virtualization-based Security (VBS) related security updates has been updated to account for the latest changes. If you deployed this policy, then you'll need to redeploy using the updated policy.

**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 Kernel memory read - unintentional read access to memory contents in kernel space from a user mode process.

**How could an attacker exploit this vulnerability?** An unauthenticated attacker could use a specially crafted application to leverage a cryptographic protocol vulnerability in Windows Kerberos to perform remote code execution against the target.

**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 Kernel memory read - unintentional read access to memory contents in kernel space from a user mode process.

**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.

**Windows 11, version 24H2 is not generally available yet. Why are there updates for this version of Windows listed in the Security Updates table?** The new Copilot+ devices that are now publicly available come with Windows 11, version 24H2 installed. Customers with these devices need to know about any vulnerabilities that affect their machine and to install the updates if they are not receiving automatic updates. Note that the general availability date for Windows 11, version 24H2 is scheduled for later this year.

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

**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.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** The authentication feature could be bypassed as this vulnerability allows impersonation.
