CVE-2025-27535 is a medium-severity vulnerability rated 5.6/10 on the CVSS scale. Exposed ioctl with insufficient access control in the firmware for some Intel(R) Ethernet Connection E825-C. before version NVM ver. EPSS estimates a 0.10% chance of exploitation in the next 30 days.

Description

Exposed ioctl with insufficient access control in the firmware for some Intel(R) Ethernet Connection E825-C. before version NVM ver. 3.84 within Ring 0: Bare Metal OS may allow a denial of service. System software adversary with a privileged user combined with a high complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
