CVE-2018-19961
CVE-2018-19961 affects the Xen hypervisor up to 4.11.x on AMD x86, where guest OS users may gain host privileges due to TLB flushes not reliably occurring after IOMMU mapping changes. Public documents confirm Xen as the affected product and describe the root cause and potential privilege escalati...
CVE-2018-19962
CVE-2018-19962 (Xen) affects the Xen hypervisor on AMD x86, where guest OS users can potentially escalate to host privileges due to small IOMMU mappings being unsafely merged into larger ones. The vulnerability is rooted in how IOMMU mappings are combined, enabling a malicious or local attacker i...

x86: DoS from attempting to use INVPCID with a non-canonical addresses
ISSUE DESCRIPTION The INVPCID instruction raises GP0 if an attempt is made to invalidate a non-canonical address. Older flushing mechanisms such as INVLPG tolerate this without error, and perform no action. There is one guest accessible path in Xen where a non-canonical address was passed into th...
insufficient TLB flushing / improper large page mappings with AMD IOMMUs
ISSUE DESCRIPTION In order to be certain that no undue access to memory is possible anymore after IOMMU mappings of this memory have been removed, Translation Lookaside Buffers TLBs need to be flushed after most changes to such mappings. Xen bypassed certain IOMMU flushes on AMD x86 hardware...
