Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: wcn36xx: se corrige el tamaño de asignación de memoria de la encuesta de canal KASAN informó un problema de asignación de memoria en wcn->chan_survey debido a un cálculo de tamaño incorrecto. Esta confirmación utiliza kcalloc para asignar memoria para wcn->chan_survey, lo que garantiza una inicialización adecuada y evita el uso de valores no inicializados cuando no hay marcos en el canal.
