CVE-2024-58059 is a vulnerability identified in the Linux kernel's media subsystem, specifically within the uvcvideo driver responsible for USB Video Class (UVC) devices such as webcams. The issue arises during the execution of the uvc_probe() function, which initializes the UVC device. If uvc_probe() fails, it may incorrectly call uvc_status_unregister() before uvc_status_init() has been invoked. This sequence leads to a deadlock condition because uvc_status_unregister() attempts to operate on a device status structure (dev->status) that may not have been properly initialized, potentially causing the kernel to hang or become unresponsive. The fix implemented involves adding a check in uvc_status_unregister() to verify whether dev->status is NULL before proceeding, thereby preventing the deadlock from occurring. This vulnerability affects Linux kernel versions containing the specified commit hash (c5fe3ed618f995b4a903e574bf2e993cdebeefca), indicating it is present in recent kernel versions prior to the patch. No known exploits are currently reported in the wild, and no CVSS score has been assigned yet. However, the vulnerability is significant because it impacts kernel stability and availability of systems using UVC devices, which are common in many environments. The issue is a logic flaw in error handling within the kernel driver, potentially leading to denial of service (DoS) conditions due to deadlocks.

For European organizations, the impact of CVE-2024-58059 primarily concerns system availability and operational continuity. Many enterprises and public sector entities rely on Linux-based systems for servers, workstations, and embedded devices. The affected uvcvideo driver is widely used for webcams and video capture devices, which are common in corporate environments for video conferencing, security surveillance, and remote collaboration. A deadlock in the kernel caused by this vulnerability could lead to system hangs or crashes, disrupting business operations, especially in environments where video devices are actively used. This could affect sectors such as finance, healthcare, government, and education, where Linux systems and video devices are prevalent. While the vulnerability does not appear to allow privilege escalation or data compromise directly, the denial of service impact could be exploited in targeted attacks to disrupt critical services. Additionally, organizations with strict uptime requirements or those using Linux in embedded or IoT devices with UVC cameras could face increased risk of operational disruption.

To mitigate CVE-2024-58059, European organizations should prioritize updating their Linux kernel to the latest patched version that includes the fix for this vulnerability. Kernel updates should be tested and deployed promptly, especially on systems utilizing UVC video devices. System administrators should audit their environments to identify devices using the uvcvideo driver and assess exposure. In environments where immediate patching is not feasible, temporary mitigation could include disabling UVC devices if they are not essential, thereby reducing the attack surface. Monitoring system logs for kernel deadlocks or unusual behavior related to video devices can help detect potential exploitation attempts. Organizations should also ensure robust backup and recovery procedures are in place to minimize downtime in case of system hangs. For embedded or IoT devices running Linux kernels with this vulnerability, vendors should be contacted for firmware updates or patches. Finally, maintaining a comprehensive vulnerability management program that includes tracking Linux kernel advisories will help ensure timely response to similar issues.
