"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nxen-netback: Zero out sring pointers on unmap\n\nIf xenvif_map_frontend_data_rings() fails when a ring is already mapped,\nit unmaps them via xenvif_unmap_frontend_data_rings() which keeps the\nring pointers unchanged. xenvif_connect_data()'s cleanup path calls\nxenvif_disconnect_queue() which in turn calls\nxenvif_unmap_frontend_data_rings() again, which will attempt to unmap the\npointers a second time.\n\nZero out the ring pointers after they are unmapped to avoid this issue.\n\nThis is XSA-532"
