CVE-2021-0105

Information disclosure and service interruption via inherited permissions

Published Jun 9, 2021 · Updated Aug 3, 2024

Incorrect permissions in Intel PROSet/Wireless WiFi drivers before 22.0 allow remote authenticated users to disclose data or disrupt service. The drivers inherit insecure permissions on an undisclosed resource, granting a highly privileged account broader access than intended. Exploitation requires adjacent access and high privileges; Intel has not identified the exposed data or precise form of service interruption.
