Quick Emulator(Qemu) built with the VMWARE PVSCSI paravirtual SCSI bus emulation support is vulnerable to an infinite loop issue. It could occur while processing an IO request descriptor, building SG list. A privileged user inside guest could use this flaw to crash the Qemu process resulting in DoS.
