CVE-2024-24861 describes a race condition found in the Linux kernel's media/xc4000 device driver, specifically in the xc4000_get_frequency() function. This vulnerability allows for a return value overflow issue, which could possibly lead to a malfunction or denial of service. The severity of this vulnerability is classified as low, with a CVSS score of 3.3. While the score indicates a lower risk, it is important for organizations to assess their exposure and potential impact.
The attack vector for this vulnerability is local, requiring low privileges and user interaction. The attack complexity is high, which may mitigate the likelihood of exploitation in certain environments. However, the potential for malfunction or service disruption remains a significant concern for organizations using affected systems.
Organizations should prioritize patching immediately to address this vulnerability, especially in environments where the Linux kernel is utilized extensively. The modification date of this vulnerability indicates ongoing attention and potential updates, which necessitates vigilance in monitoring patch releases and security advisories.
Given the low severity classification, organizations may opt to schedule remediation during their priority patch cycle. However, proactive measures, including continuous monitoring for updates and potential impacts, are recommended to mitigate risks associated with this vulnerability.
Vulnerability Details
The vulnerability is characterized by a race condition in the Linux kernel's media/xc4000 device driver. The specific function affected is xc4000_get_frequency(). This issue can lead to a return value overflow, potentially causing system malfunctions or denial of service.
The CVSS score is 3.3, indicating a low severity level. This vulnerability affects various versions of the Linux kernel, particularly those prior to version 3.0.101 and from version 6.0 to 6.7.2, as well as specific release candidates.
The official description notes that the vulnerability is classified under CWE-362, indicating a race condition issue.
Technical Analysis
The root cause of CVE-2024-24861 is identified as a race condition in the xc4000_get_frequency function of the Linux kernel's media/xc4000 device driver. This situation arises when multiple processes access shared resources concurrently without proper synchronization, leading to unpredictable behavior such as return value overflow.
The attack vector for this vulnerability is local, meaning an attacker must have access to the target system. The attack complexity is considered high, implying that successful exploitation may require specific conditions or advanced skills. Privileges required to exploit this vulnerability are low, and user interaction is required, which adds another layer of complexity.
In terms of impact, the vulnerability has no confidentiality impact, a low integrity impact, and a low availability impact. This suggests that while the risk is present, it may not lead to severe consequences under normal circumstances. However, organizations should remain vigilant as the potential for service disruption exists.
Risk & Impact Analysis
Risk to organizations includes potential service disruptions due to the malfunction caused by the race condition. The availability impact is categorized as low, but the combination of low severity and potential denial of service means that organizations must assess their specific environments to determine the actual risk.
The urgency for addressing this vulnerability is moderate. Organizations should schedule remediation, considering the potential for service interruptions, especially in critical systems where the Linux kernel is deployed.
