Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: octeontx2-pf: Evitar el uso de GFP_KERNEL en un contexto atómico. El uso de GFP_KERNEL en el contexto de deshabilitación de preempción provoca la siguiente advertencia cuando CONFIG_DEBUG_ATOMIC_SLEEP está habilitado.
