CVE-2024-43841

Kernel warning via unchecked connection SSID

Published Aug 17, 2024 · Updated May 11, 2026

Improper SSID validation in affected Linux kernels allows local users to trigger a kernel warning via a crafted virtual Wi-Fi connection. The virt_wifi connection path checks only the supplied BSSID, then reports WLAN_STATUS_SUCCESS for an unadvertised SSID, leaving cfg80211 unable to find the matching BSS. Reaching the warning requires local access to submit a connection request through virt_wifi, and the documented consequence is the warning itself.
