In the Linux kernel, a medium-severity vulnerability has been identified and resolved. This issue is associated with memory leaks in the ov2740 media driver, specifically during the initialization process of controls. Failure to properly manage memory can lead to resource leaks, which might affect system stability.
The CVSS score for this vulnerability is 5.5, indicating a medium severity level. Organizations using affected versions of the Linux kernel should take this issue seriously, as it presents a risk to the availability of systems.
The vulnerability was published on September 17, 2025, and is classified under CWE-401, indicating improper resource management. Organizations should prioritize patching immediately to ensure their systems remain secure and operational.
Currently, there is no known public exploit for this vulnerability, but organizations must remain vigilant and apply the necessary patches when available.
Organizations should assess their systems and ensure that they are using patched versions of the Linux kernel to avoid potential availability issues.
Vulnerability Details
The vulnerability allows for memory leaks during the initialization of the ov2740 media driver. This can lead to unreferenced objects in memory, increasing the risk of system instability and potentially affecting the availability of services relying on the kernel.
The vulnerability is classified under CWE-401, which refers to memory leaks. The potential impact includes high availability loss.
The Linux kernel versions affected by this vulnerability include those starting from 5.8 up to but not including 5.10.173, 5.11 up to 5.15.99, 5.16 up to 6.1.16, and 6.2 up to 6.2.3.
Technical Analysis
The root cause of the vulnerability lies in the improper handling of memory within the ov2740 media driver. The function ov2740_init_controls() fails to release allocated resources in the event of an error, leading to memory leaks.
The attack vector for this vulnerability is local, meaning that an attacker must have local access to the system to exploit it. The attack complexity is low, requiring minimal skill to trigger the memory leak.
Privileges required for exploitation are low, as the attacker does not need elevated permissions to exploit this vulnerability. Additionally, user interaction is not required, as the vulnerability can be triggered without any user action.
The impact of this vulnerability is significant in terms of availability, as it can lead to system crashes or unresponsive services. There is no confidentiality or integrity impact associated with this vulnerability.
Risk & Impact Analysis
Risk to organizations includes potential system instability and downtime due to memory leaks, which could hinder operational efficiency. The blast radius for this vulnerability can be extensive, affecting any service that relies on the Linux kernel.
Organizations should assess the impact of this vulnerability within their environments and act accordingly. The urgency for remediation is moderate, given the medium CVSS score, but it should not be overlooked.
Organizations should prioritize patching immediately to prevent any potential disruptions to services and ensure the availability of their systems.
