Description
Prasad J Pandit, Red Hat Product Security Team, reports: Qemu emulator built with the PCI MSI-X support is vulnerable to null pointer dereference issue. It occurs when the controller attempts to write to the pending bit array(PBA) memory region. Because the MSI-X MMIO support did not define the .write method. A privileges used inside guest could use this flaw to crash the Qemu process resulting in DoS issue.
