Attack Vector: Network
Attack Complexity: Low

User Interaction: Required
Scope: Unchanged
Confidentiality: High
Integrity: None
Availability: None

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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
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.

Exploitation evidence

Disclosed: evidence found.
CVE published 18 Jun 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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. Restrict access to the NVDebug tool strictly to trusted and authorized personnel with a need-to-use basis, enforcing the principle of least privilege. 2. Implement strict user authentication and session management controls to prevent unauthorized use of the tool. 3. Monitor and audit usage logs of the NVDebug tool to detect any anomalous or unauthorized access attempts promptly. 4. Educate users about the risk of social engineering or phishing attacks that could trick privileged users into interacting with malicious payloads or commands. 5. Isolate development and debugging environments from general corporate networks to limit exposure to external threats. 6. Employ network segmentation and firewall rules to restrict network access to systems running the NVDebug tool. 7. Stay vigilant for NVIDIA’s official patch releases and apply updates immediately once available. 8. Consider deploying endpoint detection and response (EDR) solutions capable of identifying suspicious activities related to debugging tools. 9. If possible, temporarily disable or uninstall the NVDebug tool on non-essential systems until a patch is available.

Description

The NVIDIA NVDebug tool contains a vulnerability that may allow an actor to gain access to restricted components. A successful exploit of this vulnerability may lead to information disclosure.

Impact

For European organizations, the impact of CVE-2025-23252 is primarily centered on confidentiality breaches within development and engineering environments that utilize NVIDIA’s NVDebug tool. Organizations involved in GPU development, high-performance computing, AI research, and industries relying on NVIDIA hardware for critical workloads may face risks of sensitive information disclosure, including proprietary debugging data or internal system details. While the vulnerability does not affect system integrity or availability, leaked information could aid attackers in crafting more sophisticated attacks or intellectual property theft. The requirement for high privileges and user interaction reduces the likelihood of widespread exploitation but does not eliminate insider threat risks or targeted attacks against development teams. European companies with advanced GPU development or research divisions, such as automotive manufacturers working on autonomous driving, AI startups, and scientific research institutions, may be particularly sensitive to this vulnerability. Additionally, the lack of available patches means organizations must rely on compensating controls until a fix is released.

CWE-1244Internal Asset Exposed to Unsafe Debug Access Level or State (opens in a new tab)
Base weakness
The product uses physical debug or test interfaces with support for multiple access levels, but it assigns the wrong debug access level to an internal asset, providing unintended access to the asset from untrusted debug agents.
Architecture and Design · Implementation
For security-sensitive assets accessible over debug/test interfaces, only allow trusted agents.
Architecture and Design
Apply blinding or masking techniques in strategic areas.
Implementation
Add shielding or tamper-resistant protections to the device, which increases the difficulty and cost for accessing debug/test interfaces.
