CVE-2025-0665 is a critical vulnerability found in Haxx and NetApp products, including libcurl and various firmware components. This vulnerability allows libcurl to incorrectly close the same eventfd file descriptor twice when shutting down a connection channel after completing a threaded name resolve. With a CVSS score of 9.8, this vulnerability poses a significant risk to organizations, potentially leading to denial of service and information disclosure.
Risk to organizations includes the high likelihood of service disruptions and data integrity issues, which could have severe implications for operational continuity. Although no known exploits are currently available, the high severity level necessitates immediate attention. Organizations should prioritize patching immediately to prevent any potential exploitation of this vulnerability.
The vulnerability was published on February 5, 2025, and is classified under CWE-1341. With increasing reliance on Haxx and NetApp products in various infrastructures, the urgency for remediation cannot be overstated. Organizations are encouraged to assess their exposure and apply necessary patches as soon as they become available.
Given the critical nature of this vulnerability, security teams should begin evaluating their systems for affected components and prepare for immediate remediation. Failure to do so could result in significant operational impacts and potential data breaches.
Vulnerability Details
The vulnerability description states that libcurl would wrongly close the same eventfd file descriptor twice when taking down a connection channel after having completed a threaded name resolve. This flaw could allow unauthorized access to sensitive system resources.
The vulnerability has a CVSS score of 9.8, indicating it is critical in severity. This score reflects high impacts on confidentiality, integrity, and availability. Affected products include curl, bootstrap_os, and various firmware versions for Haxx and NetApp products, specifically h300s_firmware, h410c_firmware, h410s_firmware, h500s_firmware, and h700s_firmware.
Technical Analysis
The root cause of this vulnerability lies in improper handling of eventfd file descriptors within the libcurl library. When a connection channel is being taken down, the library incorrectly attempts to close the same descriptor twice, leading to potential resource leakage and destabilization of the application.
This vulnerability is exploitable over the network, and it requires low attack complexity with no privileges required or user interaction necessary. The potential impacts include high confidentiality, integrity, and availability issues, making it critical for organizations to address promptly.
Risk & Impact Analysis
Organizations utilizing Haxx and NetApp products face significant risks due to the potential for service disruptions and unauthorized access to sensitive data. The blast radius could extend to critical infrastructure components, affecting overall operational capabilities. The urgency for remediation based on the CVSS score and the significant impact should prompt immediate actions.
Given the critical severity of CVE-2025-0665, organizations should engage in a thorough risk assessment to understand their exposure. Regular vulnerability scans and proactive patch management strategies should be implemented as part of a comprehensive security posture.
