I

n the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma: eDMA: Add sync read before starting the DMA transfer in remote setup The Linked list element and pointer are not stored in the same memory as the eDMA controller register. If the doorbell register is toggled before the full write of the linked list a race condition error will occur. In remote setup we can only use a readl to the memory to assure the full write has occurred.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: dmaengine: dw-edma: eDMA: Añadida lectura sincronizada antes de iniciar la transferencia DMA en la configuración remota. El elemento de la lista vinculada y el puntero no se almacenan en la misma memoria que el registro del controlador eDMA. Si el registro del timbre se activa antes de la escritura completa de la lista vinculada, se producirá un error de condición de ejecución. En la configuración remota, solo podemos usar una lectura en la memoria para asegurarnos de que se haya producido la escritura completa.
