CVE-2025-24486 is a high-severity vulnerability affecting the Linux kernel-mode driver for Intel(R) 700 Series Ethernet adapters prior to version 2.28.5. The root cause is improper input validation within the driver, which can be exploited by an authenticated local user to escalate privileges on the affected system. Specifically, the vulnerability allows a user with limited privileges to manipulate inputs in a way that compromises the kernel driver, potentially gaining elevated rights beyond their original access level. This escalation can lead to unauthorized access to sensitive system resources, modification of kernel memory, or execution of arbitrary code with kernel privileges. The vulnerability requires local access and authenticated user privileges, meaning an attacker must already have some level of access to the system, but does not require user interaction beyond that. The CVSS 4.0 base score is 8.8, reflecting the high impact on confidentiality, integrity, and availability, combined with the complexity of exploitation being high and requiring local privileges. No known exploits are currently reported in the wild, but the severity and potential impact warrant immediate attention. The vulnerability affects Linux systems using the Intel 700 Series Ethernet drivers before version 2.28.5, which are commonly found in enterprise and data center environments where Intel network adapters are deployed. Given the kernel-level nature of the flaw, successful exploitation could compromise entire systems, disrupt network communications, or facilitate lateral movement within networks.

For European organizations, this vulnerability poses a significant risk, especially for enterprises and service providers relying on Intel 700 Series Ethernet hardware in their Linux-based infrastructure. The ability for a local authenticated user to escalate privileges could lead to full system compromise, data breaches, or disruption of critical services. This is particularly concerning for sectors with stringent data protection requirements such as finance, healthcare, and government institutions within Europe. The vulnerability could be exploited by malicious insiders or attackers who have gained initial footholds through other means, enabling them to deepen their access and potentially move laterally across networks. Given the widespread use of Intel network adapters in European data centers and enterprise servers, the potential for impact is broad. Additionally, disruption or compromise of network infrastructure components could affect availability and reliability of services, impacting business continuity and regulatory compliance under frameworks like GDPR.

European organizations should prioritize updating the Intel 700 Series Ethernet Linux drivers to version 2.28.5 or later as soon as possible to remediate this vulnerability. In environments where immediate patching is not feasible, organizations should implement strict access controls to limit local user privileges and restrict access to systems with vulnerable drivers. Employing host-based intrusion detection systems (HIDS) and monitoring for unusual kernel-level activities can help detect exploitation attempts. Network segmentation should be enforced to isolate critical systems and reduce the risk of lateral movement. Additionally, organizations should review and harden user authentication policies to minimize the number of users with local access and ensure strong credential management. Regular vulnerability scanning and compliance checks should include verification of driver versions to maintain security posture. Finally, maintaining an incident response plan that includes kernel-level compromise scenarios will help organizations respond effectively if exploitation occurs.
