Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: vdpa: ifcvf: realice una limpieza adecuada si falla el inicio de IFCVF. ifcvf_mgmt_dev pierde memoria si no se libera antes de regresar. Se realiza una llamada para corregir la declaración de devolución para que no se pierda memoria. ifcvf_init_hw no se encarga de esto, por lo que es necesario hacerlo aquí.
