CVE-2024-43841: wifi: virt_wifi: avoid reporting connection success with wrong SSID

Noroxi assessment

Priority: Monitor (action score 13/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.21% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 05c4488a0e446c6ccde9f22b573950665e1cd414, 36e92b5edc8e0daa18e9325674313802ce3fbc29, 416d3c1538df005195721a200b0371d39636e05d.

Low priority for now. Upgrade to Linux Linux 05c4488a0e446c6ccde9f22b573950665e1cd414, 36e92b5edc8e0daa18e9325674313802ce3fbc29, 416d3c1538df005195721a200b0371d39636e05d or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
