Descriptions

The pvscsi_ring_pop_req_descr function in hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by leveraging failure to limit process IO loop to the ring size.

La función pvscsi_reng_pop_req_descr en hw/scsi/vmw_pvscsi.c en QEMU (también conocido como Quick Emulator) permite a administradores locales del SO invitado provocar una denegación de servicio (bucle infinito y caída del proceso QEMU) al aprovechar el fallo para limitar el bucle IO del proceso para el tamaño del anillo.
