CVE-2025-39919

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: add missing check for rx wcid entries Non-station wcid entries must not be passed to the rx functions. In case of the global wcid entry, it could even lead to corruption in the wcid array due to pointer being casted to struct mt7996_sta_link using container_of.

Summary		(es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: wifi: mt76: mt7996: añadir verificación faltante para entradas rx wcid Las entradas wcid que no son de estación no deben pasarse a las funciones rx. En el caso de la entrada wcid global, podría incluso llevar a corrupción en el array wcid debido a que el puntero es casteado a la estructura mt7996_sta_link usando container_of.
