CVE-2025-20093 is a local privilege escalation vulnerability in the Linux kernel-mode driver for some Intel 800 Series Ethernet controllers. According to the provided content, the flaw is caused by an improper check for unusual or exceptional conditions in driver versions prior to 1.17.2. Because the affected component runs in kernel space, an authenticated local user may be able to trigger mishandling of exceptional states, leading to unintended code paths, driver state corruption, or kernel-memory-adjacent effects that can be leveraged for privilege escalation. The issue is documented by Intel in INTEL-SA-01296 and affects Linux systems using the vulnerable Intel 800 Series Ethernet driver.
