Attack Vector: Local
Attack Complexity: Low

Vulnerable system confidentiality: None
Vulnerable system integrity: None
Vulnerable system availability: Low
Subsequent system confidentiality: None
Subsequent system integrity: None
Subsequent system availability: None

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

Attack Vector: Local: The vulnerable system is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or through terminal emulation (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., using social engineering techniques to trick a legitimate user into opening a malicious document).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Disclosed: evidence found.
CVE published 12 Aug 2025
Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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 26 Oct 2026.

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 or the CVSS exploit maturity 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.

What to do

Upgrade Intel(R) 700 Series Ethernet to 2.28.5.

AI-suggested

To mitigate this vulnerability, European organizations should prioritize updating the Intel 700 Series Ethernet Linux driver to version 2.28.5 or later as soon as it becomes available. If you cannot patch yet, organizations should restrict local access to systems with vulnerable drivers, enforcing strict access controls and monitoring for unusual resource consumption patterns indicative of exploitation attempts. Network segmentation and limiting user privileges can reduce the attack surface. Additionally, implementing host-based intrusion detection systems (HIDS) to monitor for abnormal driver or network interface behavior can provide early warning. Regular auditing of installed driver versions and maintaining an up-to-date asset inventory will help identify affected systems promptly. For critical systems, consider temporary disabling or replacing vulnerable network adapters if patching is delayed. Finally, educating system administrators about this vulnerability and ensuring timely application of vendor updates is essential.

Description

Uncontrolled resource consumption in the Linux kernel-mode driver for some Intel(R) 700 Series Ethernet before version 2.28.5 may allow an authenticated user to potentially enable denial of service.

Impact

For European organizations, the impact of this vulnerability primarily concerns availability of network services on systems using Intel 700 Series Ethernet adapters with the vulnerable Linux driver. Organizations relying on these network interfaces for critical infrastructure, data centers, or enterprise networks could experience service disruptions if an attacker with local access exploits this vulnerability to cause denial of service. This could affect operational continuity, especially in sectors with high availability requirements such as finance, telecommunications, healthcare, and government services. Since exploitation requires authenticated local access, the risk is higher in environments where multiple users have access to systems or where attackers can gain foothold through other means. The vulnerability does not compromise data confidentiality or integrity directly but can degrade network reliability and availability, potentially impacting business operations and service level agreements.
