Insufficient Access Control in Intel Ethernet Firmware

CVE-2025-27535

What is CVE-2025-27535?

The vulnerability in Intel Ethernet Connection E825-C firmware arises from exposed ioctl with insufficient access control. This may allow a privileged user to exploit the system's firmware, potentially leading to a denial of service. For attack success, local access is required, facilitating unauthorized operations without the need for user interaction. Although the vulnerability does not compromise data confidentiality or integrity, it significantly threatens the availability of affected systems, which could disrupt operations and services.
