CVE-2025-38420

In the Linux kernel, the following vulnerability has been resolved: wifi: carl9170: do not ping device which has failed to load firmware Syzkaller reports [1, 2] crashes caused by an attempts to ping the device which has failed to load firmware. Since such a device doesn't pass 'ieee80211_register_hw()', an internal workqueue managed by 'ieee80211_queue_work()' is not yet created and an attempt to queue work on it causes null-ptr-deref.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: carl9170: no hacer ping al dispositivo que no ha podido cargar el firmware. Syzkaller reporta [1, 2] fallos causados por intentos de hacer ping al dispositivo que no ha podido cargar el firmware. Dado que dicho dispositivo no supera la prueba 'ieee80211_register_hw()', aún no se crea una cola de trabajo interna administrada por 'ieee80211_queue_work()' y cualquier intento de cola de trabajo en ella provoca un error de referencia nulo (PTR).
