Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Adjacent: The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.
Exploit Code Maturity: Unproven: No exploit code is available, or an exploit is theoretical.
Remediation Level: Official Fix: A complete vendor solution is available. Either the vendor has issued an official patch, or an upgrade is available.
Report Confidence: Confirmed: Detailed reports exist, or functional reproduction is possible (functional exploits may provide this). Source code is available to independently verify the assertions of the research, or the author or vendor of the affected code has confirmed the presence of the vulnerability.

Detectable: no evidence on record.

No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

1. Monitor Microsoft security advisories closely and apply official patches for Windows 11 Version 24H2 Hyper-V as soon as they are released. 2. Restrict network access to Hyper-V management and virtual network interfaces to trusted and authenticated devices only, minimizing adjacent network exposure. 3. Implement network segmentation to isolate Hyper-V hosts and virtual machines from less trusted network segments. 4. Use host-based intrusion detection systems (HIDS) and network intrusion detection systems (NIDS) to monitor for unusual traffic patterns or attempts to exploit Hyper-V vulnerabilities. 5. Limit the number of users with privileges to manage or access Hyper-V environments, enforcing the principle of least privilege. 6. Conduct regular vulnerability assessments and penetration testing focusing on virtualization infrastructure. 7. Maintain comprehensive logging and audit trails for Hyper-V operations to detect potential exploitation attempts. 8. Educate IT staff about the risks associated with virtualization vulnerabilities and the importance of timely patching and network controls.

Description

Integer overflow or wraparound in Windows Hyper-V allows an authorized attacker to disclose information over an adjacent network.

Impact

The primary impact of CVE-2025-48002 is the unauthorized disclosure of sensitive information due to an integer overflow in Hyper-V on Windows 11 24H2. For European organizations, this could lead to leakage of confidential data within virtualized environments, potentially exposing intellectual property, personal data, or security credentials. Sectors with heavy reliance on virtualization, such as finance, healthcare, government, and critical infrastructure, are particularly at risk. The vulnerability does not affect system integrity or availability, so direct disruption or data manipulation is unlikely. However, information disclosure can facilitate further attacks, including targeted intrusions or lateral movement within networks. The requirement for adjacent network access and low privileges limits the attack surface but does not eliminate risk, especially in complex enterprise networks where internal threat actors or compromised devices may exist. The absence of known exploits reduces immediate risk but does not preclude future exploitation. European organizations must consider the potential regulatory impact of data breaches under GDPR if sensitive personal data is exposed.

CWE-190Integer Overflow or Wraparound (opens in a new tab)
Base weaknessLikelihood of exploit: Medium
The product 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 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 become a very small or negative number.
Requirements
Ensure that all protocols are strictly defined, such that all out-of-bounds behavior can be identified simply, and require strict conformance to the protocol.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
