Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: dma-buf: inserta una barrera de memoria antes de actualizar num_fences. smp_store_mb() inserta una barrera de memoria después de la operación de almacenamiento. Esto difiere del objetivo original del comentario, por lo que puede producirse una desreferencia de puntero nulo si se reordena la actualización de memoria.
