CVE-2024-53059 is a vulnerability identified in the Linux kernel's wireless driver component, specifically within the iwlwifi module that manages Intel wireless network adapters. The vulnerability arises from improper handling of response packets in the function iwl_mvm_send_recovery_cmd(). Two critical issues are present: first, the size of the response packet is not validated, which can lead to potential buffer overflows or memory corruption; second, the response buffer is not freed after processing, causing a memory leak. Both issues can degrade system stability or potentially be exploited to execute arbitrary code or cause denial of service. The fix involves replacing the vulnerable function call with iwl_mvm_send_cmd_status(), which properly validates the size of the response and ensures the buffer is freed, thus mitigating the risk. Since this vulnerability affects the Linux kernel's wireless driver, it impacts any Linux-based system using affected versions of the iwlwifi driver, which is common in many laptops, servers, and embedded devices using Intel Wi-Fi hardware. No known exploits are currently reported in the wild, and no CVSS score has been assigned yet.

For European organizations, this vulnerability poses a risk primarily to systems running Linux with Intel wireless adapters using the affected iwlwifi driver versions. Potential impacts include system crashes or denial of service due to memory leaks and buffer overflows, which can disrupt business operations, especially in environments relying on wireless connectivity. More critically, if exploited, it could allow attackers to execute arbitrary code with kernel privileges, compromising confidentiality, integrity, and availability of affected systems. This risk is heightened in sectors with high reliance on Linux infrastructure such as telecommunications, finance, research institutions, and government agencies. The absence of known exploits reduces immediate risk, but the widespread use of Linux and Intel Wi-Fi hardware in Europe means that unpatched systems remain vulnerable to future attacks once exploit code becomes available.

European organizations should prioritize updating their Linux kernel and iwlwifi driver to the patched versions that replace iwl_mvm_send_recovery_cmd() with iwl_mvm_send_cmd_status(). This update ensures proper validation and memory management. System administrators should audit their environments to identify devices using Intel wireless adapters and verify kernel versions. Employing automated patch management tools can accelerate deployment of fixes. Additionally, monitoring wireless driver logs for anomalies and unusual crashes can help detect exploitation attempts. Network segmentation and limiting unnecessary wireless access can reduce attack surface. For critical systems, consider temporary disabling wireless interfaces until patches are applied. Finally, maintain up-to-date backups and incident response plans to mitigate potential impacts from exploitation.
