CVE-2024-27068 is a vulnerability identified in the Linux kernel, specifically within the thermal driver for MediaTek devices (lvts_thermal). The issue arises from a memory leak in an error handling path where the function devm_krealloc() fails. In this failure scenario, a resource named 'efuse' is not properly freed, leading to a memory leak. Memory leaks occur when allocated memory is not released back to the system, which can degrade system performance over time and potentially lead to resource exhaustion. This vulnerability is located in a low-level hardware driver component responsible for thermal management on MediaTek platforms integrated into the Linux kernel. The fix involves ensuring that the 'efuse' resource is freed when devm_krealloc() fails, preventing the leak. There are no known exploits in the wild for this vulnerability, and no CVSS score has been assigned yet. The affected versions are identified by specific commit hashes, indicating that this is a recent and targeted fix in the kernel source code. The vulnerability does not appear to allow direct code execution or privilege escalation but could impact system stability and availability if the leak accumulates over time, especially in embedded or resource-constrained environments using affected MediaTek hardware.

For European organizations, the impact of CVE-2024-27068 is primarily related to system stability and availability rather than direct compromise of confidentiality or integrity. Organizations using Linux-based systems with MediaTek hardware components, particularly in embedded devices, IoT, or specialized industrial equipment, could experience degraded performance or system crashes if the memory leak is triggered repeatedly. This could affect sectors relying on such devices for critical infrastructure, manufacturing, or telecommunications. However, since the vulnerability is a memory leak in a specific thermal driver and does not enable remote code execution or privilege escalation, the risk of direct cyberattack exploitation is low. The impact is more operational, potentially leading to increased maintenance costs or downtime if systems are not patched. European organizations with large deployments of Linux on MediaTek platforms should prioritize patching to maintain system reliability and avoid potential disruptions in service.

To mitigate CVE-2024-27068, European organizations should: 1) Apply the latest Linux kernel updates that include the patch fixing the memory leak in the MediaTek lvts_thermal driver. This is the most effective and direct mitigation. 2) Identify and inventory all systems running Linux kernels with MediaTek thermal drivers, focusing on embedded devices, IoT, and specialized hardware. 3) Monitor system logs and performance metrics for signs of memory leaks or resource exhaustion related to thermal management components. 4) For devices that cannot be immediately updated, consider implementing system-level resource monitoring and automated reboots or resets to prevent prolonged degradation. 5) Engage with hardware and software vendors to confirm the presence of the patch in their Linux distributions and firmware updates. 6) Incorporate this vulnerability into existing vulnerability management and patching workflows to ensure timely remediation.
