Guest triggerable qemu MSI-X pass-through error messages

ISSUE DESCRIPTION Device model code dealing with guest PCI MSI-X interrupt management activities logs messages on certain supposedly invalid guest operations. IMPACT A buggy or malicious guest repeatedly invoking such operations may result in the host disk to fill up, possibly leading to a Denial...

Potential unintended writes to host MSI message data field via qemu

ISSUE DESCRIPTION Logic is in place to avoid writes to certain host config space fields when the guest must nevertheless be able to access their virtual counterparts. A bug in how this logic deals with accesses spanning multiple fields allows the guest to write to the host MSI message data field...

Unmediated PCI register access in qemu

ISSUE DESCRIPTION Qemu allows guests to not only read, but also write all parts of the PCI config space but not extended config space of passed through PCI devices not explicitly dealt with for partial emulation purposes. IMPACT Since the effect depends on the specific purpose of the the config...
