CVE-2021-0177

Unauthenticated service interruption from adjacent networks

Published Feb 9, 2022 · Updated May 5, 2025

Input consistency validation in Intel PROSet/Wireless Wi-Fi and Killer Wi-Fi allows remote attackers to interrupt service from an adjacent network. Intel has not published the affected software locus or the inconsistent input operation that triggers the failure. The flaw requires no authentication but is limited to Windows 10 and 11 systems within adjacent-network reach, and the reported consequence is availability loss without data disclosure or modification.
