  "message": "Fix NULL pointer dereference in vPortGetHeapStats\n\nWhen the heap is exhausted (no free block), start and end markers are\nthe only blocks present in the free block list:\n\n     +---------------+     +-----------\u003e NULL\n     |               |     |\n     |               V     |\n+ ----- +            + ----- +\n|   |   |            |   |   |\n|   |   |            |   |   |\n+ ----- +            + ----- +\n  xStart               pxEnd\n\nThe code block which traverses the list of free blocks to calculate heap\nstats used a do..while loop that moved past the end marker when the heap\nhad no free block resulting in a NULL pointer dereference. This commit\nchanges the do..while loop to while loop thereby ensuring that we never\nmove past the end marker.\n\nThis was reported here - https://github.com/FreeRTOS/FreeRTOS-Kernel/issues/534\n\nSigned-off-by: Gaurav Aggarwal \u003caggarg@amazon.com\u003e\n",
