Jul 2024: Windows Hyper-V Elevation of Privilege Vulnerability
CVE-2024-38080 Published on July 9, 2024
Windows Hyper-V Elevation of Privilege Vulnerability
Windows Hyper-V Elevation of Privilege Vulnerability
Known Exploited Vulnerability
This Microsoft Windows Hyper-V Privilege Escalation Vulnerability is part of CISA's list of Known Exploited Vulnerabilities. Microsoft Windows Hyper-V contains a privilege escalation vulnerability that allows a local attacker with user permissions to gain SYSTEM privileges.
The following remediation steps are recommended / required by July 30, 2024: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Weakness Type
Integer Overflow or Wraparound
The software performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. An integer overflow or wraparound occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may wrap to become a very small or negative number. While this may be intended behavior in circumstances that rely on wrapping, it can have security consequences if the wrap is unexpected. This is especially the case if the integer overflow can be triggered using user-supplied inputs. This becomes security-critical when the result is used to control looping, make a security decision, or determine the offset or size in behaviors such as memory allocation, copying, concatenation, etc.
