Vulnerability in Linux
CVE-2025-38642
In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix WARN_ON for monitor mode on some devices On devices without WANT_MONITOR_VIF (and probably without channel context support) we get a WARN_ON for changing the per-link setting of a monitor interface. Since we already skip AP_VLAN interfaces and MONITOR with WANT_MONITOR_VIF and/or NO_VIRTUAL_MONITOR should update the settings, catch this in the link change code instead of the warning.
