CVE-2024-43841: Linux Kernel

Low severity, CVSS 3.3. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: wifi: virt_wifi: avoid reporting connection success with wrong SSID When user issues a connection with a different SSID than the one virt_wifi has advertised, the __cfg80211_connect_result() will trigger the warning: WARN_ON(bss_not_found). The issue is because the connection code in virt_wifi does not check the SSID from user space (it only checks the BSSID), and virt_wifi will call cfg80211_connect_result() with WLAN_STATUS_SUCCESS even if the SSID is different from the one virt_wifi has advertised. Eventually cfg80211 won't be able to find the cfg80211_bss and generate the warning. Fixed it by checking the SSID (from user space) in the connection code.

Affected products

• Linux Linux Kernel: from 5.0, before 6.1.103 (fixed in 6.1.103); from 6.2, before 6.6.44 (fixed in 6.6.44); from 6.7, before 6.10.3 (fixed in 6.10.3)
