CVE-2024-38805 is a medium-severity vulnerability identified in EDK2, specifically related to its BIOS functionality. This vulnerability allows an attacker to cause an integer overflow or wraparound through network means. The successful exploitation of this vulnerability may lead to denial of service, impacting system availability and functionality.
The CVSS score assigned to this vulnerability is 6.3, categorizing it as medium severity. This score indicates that while the attack complexity is low and requires only low privileges, the potential availability impact is high. Organizations utilizing EDK2 should prioritize understanding this vulnerability as it may pose significant risks to system operations.
Given the nature of the vulnerability and its potential for exploitation, organizations are urged to assess their systems and implement necessary mitigations as part of their security protocols. Immediate attention is necessary to prevent any disruptions that could arise from this vulnerability.
As of now, the vulnerability is classified as 'Awaiting Analysis,' indicating that comprehensive evaluations and recommendations are forthcoming. However, organizations should not delay in assessing their exposure and preparing for potential remediation strategies.
Vulnerability Details
This vulnerability allows for an integer overflow or wraparound by network means in the EDK2 BIOS. The official CVE description highlights the risk of denial of service that may result from successful exploitation. The CVSS 3.1 score is 6.3, reflecting the medium severity of this vulnerability.
Affected systems include those running the EDK2 BIOS, though specific versions are not detailed in the current information. The publication date for this CVE is August 12, 2025, and it has been assigned a CWE classification of CWE-190, which pertains to integer overflow.
Technical Analysis
The root cause of this vulnerability lies in the handling of integer values within the BIOS. An integer overflow occurs when an operation attempts to create a numeric value that is too high to be represented within the available storage space, leading to unexpected behavior. In this case, the overflow can be exploited through adjacent network access.
The attack complexity is assessed as low, meaning that attackers do not require significant expertise or resources to exploit this vulnerability. Privileges required for exploitation are categorized as low, indicating that basic user access may be sufficient. Importantly, user interaction is not required to trigger this vulnerability.
The impacts of a successful attack include integrity compromise and high availability impact, which suggests that systems may be rendered inoperable. Confidentiality is not affected, highlighting that the primary risk centers around service disruption.
Risk & Impact Analysis
Risk to organizations includes potential downtime and service interruption due to denial of service. As systems may become unavailable due to exploitation of the integer overflow, the operational integrity can be severely impacted. Organizations should assess their deployment of EDK2 and consider the potential blast radius of this vulnerability.
The urgency of addressing this vulnerability is underscored by its medium CVSS score. Organizations should schedule remediation as part of their security management practices. The risk of denial of service can affect not just individual systems but potentially broader network operations, making timely patching essential.
