CVE-2025-24324 is a vulnerability identified in the Linux kernel-mode driver for Intel(R) 800 Series Ethernet adapters, specifically affecting versions prior to 1.17.2. The flaw arises from an integer overflow or wraparound condition within the driver code. This type of vulnerability occurs when an arithmetic operation attempts to create a numeric value that is outside the range that can be represented with a given number of bits, causing the value to wrap around to an unintended number. In this case, the overflow can lead to improper handling of memory or data structures within the driver. Exploitation requires local authenticated access, meaning an attacker must already have some level of access to the system. By leveraging this vulnerability, an attacker with limited privileges could potentially escalate their privileges to a higher level, such as root or kernel-level access, thereby gaining greater control over the affected system. The vulnerability does not require user interaction and has a CVSS 4.0 base score of 2, indicating low severity. The attack vector is local (AV:L), with high attack complexity (AC:H), and requires low privileges (PR:L). There is no known exploitation in the wild as of the publication date, and no patches or exploit code links have been provided yet. The vulnerability impacts the integrity and potentially the confidentiality of the system by allowing privilege escalation, but it does not affect availability. The scope is limited to systems using the vulnerable Intel Ethernet drivers on Linux, and the attacker must already have authenticated local access, limiting the ease of exploitation and the breadth of affected systems.

For European organizations, the impact of CVE-2025-24324 is primarily on systems running Linux with Intel 800 Series Ethernet adapters using the vulnerable driver versions. Organizations with critical infrastructure, data centers, or enterprise environments that rely on these network adapters could face risks if an attacker gains local access to a system. Privilege escalation vulnerabilities can lead to unauthorized access to sensitive data, modification of system configurations, or deployment of persistent malware. However, the requirement for local authenticated access and high attack complexity reduces the likelihood of widespread exploitation. Nonetheless, in environments where insider threats exist or where attackers have already compromised low-privilege accounts, this vulnerability could be leveraged to deepen access and cause significant damage. Given the prevalence of Linux in server environments across Europe, especially in sectors like finance, telecommunications, and government, the vulnerability warrants attention. The low CVSS score suggests limited immediate risk, but the potential for privilege escalation means that targeted attacks could have serious consequences for confidentiality and integrity of systems.

To mitigate the risk posed by CVE-2025-24324, European organizations should prioritize the following actions: 1) Update the Intel 800 Series Ethernet Linux kernel-mode driver to version 1.17.2 or later as soon as the patch becomes available from Intel or through Linux distribution updates. 2) Implement strict access controls to limit local user accounts and reduce the number of users with authenticated access to critical systems. 3) Employ robust monitoring and logging to detect unusual privilege escalation attempts or suspicious local activity on systems using the affected drivers. 4) Use security tools to enforce least privilege principles and restrict the ability of low-privilege users to execute code or access sensitive kernel modules. 5) Conduct regular vulnerability assessments and penetration testing focusing on local privilege escalation vectors. 6) Harden Linux systems by disabling unnecessary services and network interfaces to reduce the attack surface. 7) Educate system administrators and users about the risks of local privilege escalation and the importance of applying security updates promptly. These measures go beyond generic advice by focusing on controlling local access, monitoring for exploitation attempts, and ensuring timely patching specific to the Intel Ethernet driver vulnerability.
