CVE-2025-38642
Full vulnerability record from the local CVENow database.
Description
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.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: mac80211: corrección de WARN_ON para el modo monitor en algunos dispositivos. En dispositivos sin WANT_MONITOR_VIF (y probablemente sin compatibilidad con contexto de canal), recibimos un WARN_ON al cambiar la configuración por enlace de una interfaz de monitor. Dado que ya omitimos las interfaces AP_VLAN y MONITOR con WANT_MONITOR_VIF o NO_VIRTUAL_MONITOR debería actualizar la configuración, se debe incluir esto en el código de cambio de enlace en lugar de la advertencia."
