CVE-2024-39779

Local service interruption via driver stack overflow

Published Feb 12, 2025 · Updated Feb 13, 2025

Stack-based buffer overflow in Intel Ethernet Connection I219 Series drivers before 12.19.1.39 allows local users to interrupt service. Intel has not published the affected driver routine or the unchecked operation that overruns its stack buffer. Exploitation requires authenticated local access and high attack complexity, and the documented consequence is loss of driver availability.
