CVE-2024-27074 is a memory leak vulnerability identified in the Linux kernel's media subsystem, specifically within the go7007 driver used for certain video capture devices. The issue arises in the function go7007_load_encoder, where a memory allocation for a buffer named 'bounce' (go->boot_fw) occurs without a corresponding deallocation. The call chain leading to this leak starts from saa7134_go7007_init, which calls go7007_boot_encoder, then go7007_load_encoder, and finally kfree(go). While the 'go' structure is freed, the 'bounce' buffer remains allocated, resulting in a memory leak. This leak can cause gradual consumption of kernel memory resources over time, potentially leading to degraded system performance or instability. The vulnerability affects multiple versions of the Linux kernel identified by the commit hash 95ef39403f890360a3e48fe550d8e8e5d088ad74. No known exploits are currently reported in the wild, and no CVSS score has been assigned. The flaw is a resource management bug rather than a direct code execution or privilege escalation vulnerability. However, persistent memory leaks in kernel space can indirectly affect system reliability and availability, especially in systems heavily utilizing the affected media drivers.

For European organizations, the impact of CVE-2024-27074 primarily concerns systems running Linux kernels with the affected go7007 media driver, commonly used in video capture or TV tuner hardware. Organizations relying on such hardware for media processing, broadcasting, or surveillance could experience gradual system degradation due to kernel memory leaks. This may lead to increased system crashes, reboots, or degraded performance, impacting operational continuity. While the vulnerability does not directly compromise confidentiality or integrity, availability could be affected if the leak causes kernel instability. Critical infrastructure or media companies in Europe using these devices might face operational disruptions. Additionally, embedded systems or IoT devices running affected Linux kernels could experience reduced reliability. Since no known exploits exist, the immediate risk is low, but prolonged exposure without patching could increase the likelihood of denial-of-service conditions.

To mitigate CVE-2024-27074, European organizations should: 1) Identify and inventory all systems using the go7007 driver or related media capture hardware. 2) Apply the latest Linux kernel patches that address this memory leak as soon as they become available from trusted sources or Linux distributions. 3) For systems where immediate patching is not feasible, consider disabling the go7007 driver if the hardware is not critical to operations. 4) Monitor system logs and kernel memory usage for unusual increases that could indicate memory leaks. 5) Implement routine system reboots as a temporary measure to clear leaked memory and maintain system stability. 6) Engage with hardware vendors to confirm firmware updates or driver patches that may further mitigate the issue. 7) Maintain up-to-date backups and incident response plans to quickly recover from potential system outages caused by this vulnerability.
