Unauthenticated system crash via malformed Layer-2 input
Published Jul 9, 2024 · Updated Feb 10, 2026
Improper input validation in the Microsoft Windows Layer-2 Bridge Network Driver allows remote attackers on an adjacent network to crash affected systems. Microsoft has not disclosed the packet field or driver routine that accepts and mishandles the malformed Layer-2 network input. Exploitation requires adjacent-network access but no authentication or user interaction, and the reported consequence is a system crash without confidentiality or integrity impact.
