CVE-2020-0558

Denial of service via improper driver buffer restrictions

Published Apr 15, 2020 · Updated Aug 4, 2024

Buffer-restriction flaw in the Windows 10 kernel driver for Intel PROSet/Wireless WiFi before 21.70 allows attackers to interrupt service. Intel identifies improper buffer restrictions in the kernel-mode driver but does not disclose the driver file, input field, or exact buffer operation. The attack requires adjacent-network access and no prior privileges; the reported consequence is service interruption with no confidentiality or integrity impact.
