| Xen 3.3.x through 4.5.x and the Linux kernel through 3.19.1 do not properly restrict access to PCI command registers, which might allow local guest OS users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response. | |||||
| CVE-2016-3961 | 2 Canonical, Xen | 2 Ubuntu Linux, Xen | 2025-04-12 | 2.1 LOW | 5.5 MEDIUM |
| Xen and the Linux kernel through 4.5.x do not properly suppress hugetlbfs support in x86 PV guests, which allows local PV guest OS users to cause a denial of service (guest OS crash) by attempting to access a hugetlbfs mapped area. | |||||
| CVE-2014-2580 | 1 Xen | 1 Xen | 2025-04-12 | 4.4 MEDIUM | N/A |
| The netback driver in Xen, when using certain Linux versions that do not allow sleeping in softirq context, allows local guest administrators to cause a denial of service ("scheduling while atomic" error and host crash) via a malformed packet, which causes a mutex to be taken when trying to disable the interface. | |||||
| CVE-2014-8595 | 3 Debian, Opensuse, Xen | 3 Debian Linux, Opensuse, Xen | 2025-04-12 | 1.9 LOW | N/A |
| arch/x86/x86_emulate/x86_emulate.c in Xen 3.2.1 through 4.4.x does not properly check privileges, which allows local HVM guest users to gain privileges or cause a denial of service (crash) via a crafted (1) CALL, (2) JMP, (3) RETF, (4) LCALL, (5) LJMP, or (6) LRET far branch instruction. | |||||
