CVE-2025-38293
Estado: ModificadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: fix node corruption in ar->arvifs list
In current WLAN recovery code flow, ath11k_core_halt() only reinitializes the "arvifs" list head. This will cause the list node immediately following the list head to become an invalid list node. Because the prev of that node still points to the list head "arvifs", but the next of the list head "arvifs" no longer points to that list node.
When a WLAN recovery occurs during the execution of a vif removal, and it happens before the spin_lock_bh(&ar->data_lock) in ath11k_mac_op_remove_interface(), list_del() will detect the previously mentioned situation, thereby triggering a kernel panic.

The fix is to remove and reinitialize all vif list nodes from the list head "arvifs" during WLAN halt. The reinitialization is to make the list nodes valid, ensuring that the list_del() in ath11k_mac_op_remove_interface() can execute normally.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: ath11k: corrección de corrupción de nodos en la lista ar->arvifs. En el flujo de código de recuperación de WLAN actual, ath11k_core_halt() solo reinicializa la cabecera de lista \"arvifs\". Esto provocará que el nodo de lista inmediatamente posterior a la cabecera de lista se convierta en un nodo de lista inválido. Esto se debe a que el nodo anterior de ese nodo aún apunta a la cabecera de lista \"arvifs\", pero el siguiente ya no apunta a ese nodo. Cuando se produce una recuperación de WLAN durante la ejecución de una eliminación de vif, y esto ocurre antes de spin_lock_bh(&ar->data_lock) en ath11k_mac_op_remove_interface(), list_del() detectará la situación mencionada anteriormente, lo que activará un pánico del kernel. La solución consiste en eliminar y reinicializar todos los nodos de lista vif de la cabecera de lista \"arvifs\" durante la detención de WLAN. La reinicialización sirve para hacer que los nodos de la lista sean válidos, garantizando que list_del() en ath11k_mac_op_remove_interface() pueda ejecutarse normalmente.
