CVE-2024-27076 addresses a memory leak vulnerability in the Linux kernel specifically within the media subsystem's imx driver, which handles color space conversion (csc) and scaling operations. The vulnerability arises from improper memory management in the v4l2_ctrl_handler component, which is responsible for handling video4linux2 (v4l2) control operations. The issue occurs because the memory allocated during the initialization of v4l2_ctrl_handler (via v4l2_ctrl_handler_init) is not properly freed upon release, leading to a memory leak. Over time, this leak can cause increased memory consumption, potentially degrading system performance or causing denial of service (DoS) conditions due to resource exhaustion. The fix involves ensuring that the allocated memory is correctly freed when the control handler is released, thus preventing the leak. This vulnerability affects specific versions of the Linux kernel as identified by the commit hashes provided, and it is relevant to systems using the imx media driver, which is typically found in embedded devices and platforms utilizing i.MX processors. There are no known exploits in the wild at this time, and no CVSS score has been assigned yet. The vulnerability does not appear to allow direct code execution or privilege escalation but can impact system stability and availability through resource depletion.

For European organizations, the primary impact of CVE-2024-27076 lies in potential system instability and denial of service on devices running affected Linux kernel versions with the imx media driver enabled. This is particularly relevant for industries relying on embedded Linux systems, such as automotive, industrial control, telecommunications, and IoT deployments, where i.MX processors are common. Memory leaks can lead to gradual degradation of system performance, unexpected reboots, or crashes, which can disrupt critical operations and services. While this vulnerability does not directly compromise confidentiality or integrity, the availability impact can be significant in environments requiring high uptime and reliability. Organizations using Linux-based media processing or video capture devices should be aware of this issue to prevent operational disruptions. Since no active exploits are known, the immediate risk is moderate, but unpatched systems could become targets if attackers develop exploitation techniques that leverage resource exhaustion to cause denial of service.

European organizations should prioritize updating their Linux kernel to versions that include the patch for CVE-2024-27076. Specifically, they should track kernel releases and vendor advisories for the imx media driver fixes. For embedded and IoT devices where kernel updates may be less frequent, organizations should implement monitoring of system memory usage and set alerts for abnormal increases that could indicate a memory leak. Employing watchdog timers to automatically reboot devices experiencing resource exhaustion can mitigate prolonged downtime. Additionally, organizations should audit their device inventory to identify systems using i.MX processors and the affected Linux kernel versions. Where possible, disabling or limiting the use of the imx media driver if not required can reduce exposure. Finally, maintaining robust patch management processes and testing updates in controlled environments before deployment will ensure stability and security.
