CVE-2025-38642

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix WARNON for monitor mode on some devices On devices without WANTMONITORVIF and probably without channel context support we get a WARNON for changing the per-link setting of a monitor interface. Since we already...

CVE-2025-38642

CVE-2025-38642 affects the Linux kernel’s wifi/mac80211 monitor mode handling. The issue arises on devices without WANT_MONITOR_VIF (and likely without channel context support), triggering a WARN_ON when modifying the per-link settings of a MONITOR interface. The fix moves this validation from a ...
