CVE-2013-6400
Last modified
CVE-2013-6400 is a vulnerability of currently unknown severity. Xen 4.2.x and 4.3.x, when using Intel VT-d and a PCI device has been assigned, does not clear the flag that suppresses IOMMU TLB flushes when unspecified errors occur, which causes the TLB entries to not be flushed and allows local guest administrators to cause a denial of service (host crash) or gain privileges via unspecified vectors.. EPSS estimates a 0.66% chance of exploitation in the next 30 days.
