CVE-2025-24303

Local privilege escalation

Published Aug 12, 2025 · Updated Feb 26, 2026

Improper condition handling in the Intel 800 Series Ethernet Linux Kernel Mode Driver before 1.17.2 allows local users to elevate privileges. Intel has not disclosed the code locus, exceptional condition, or operation that mishandles it. Exploitation requires low-privileged local access, high attack complexity, and no user interaction; success crosses a security boundary and compromises confidentiality, integrity, and availability.
