| The physdev_get_free_pirq hypercall in arch/x86/physdev.c in Xen 4.1.x and Citrix XenServer 6.0.2 and earlier uses the return value of the get_free_pirq function as an array index without checking that the return value indicates an error, which allows guest OS users to cause a denial of service (invalid memory write and host crash) and possibly gain privileges via unspecified vectors. | |||||
| CVE-2016-2270 | 4 Debian, Fedoraproject, Oracle and 1 more | 4 Debian Linux, Fedora, Vm Server and 1 more | 2017-06-30 | 4.6 MEDIUM | 6.8 MEDIUM |
