Description

A NULL pointer dereference vulnerability was found in the QEMU emulator built with PCI MSI-X support. Because MSI-X MMIO support did not define the .write method, when the controller tried to write to the pending bit array(PBA) memory region, a segmentation fault occurred. A privileged attacker inside the guest could use this flaw to crash the QEMU process resulting in denial of service.
