  3. CVE-2025-38570
In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: unlink NAPIs from queues on error to open CI hit a UaF in fbnic in the AF_XDP portion of the queues.py test. The UaF is in the __sk_mark_napi_id_once() call in xsk_bind(), NAPI has been freed. Looks like the device failed to open earlier, and we lack clearing the NAPI pointer from the queue.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: eth: fbnic: al desvincular NAPIs de las colas en caso de error al abrir CI, se encontró una UaF en fbnic en la sección AF_XDP de la prueba queues.py. La UaF se encuentra en la llamada __sk_mark_napi_id_once() en xsk_bind(); la NAPI se ha liberado. Parece que el dispositivo no se abrió previamente y nos falta borrar el puntero NAPI de la cola.
