2017-07-05 CVE-2017-10912 Xen through 4.8.x mishandles page transfer, which allows guest OS users to obtain privileged host OS access, aka XSA-217. Xen 10.0
2016-04-13 CVE-2015-8553 Xen allows guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory by not enabling memory and I/O decoding control bits. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-0777. Enterprise_linux, Xen 6.5
2017-08-24 CVE-2017-12136 Race condition in the grant table code in Xen 4.6.x through 4.9.x allows local guest OS administrators to cause a denial of service (free list corruption and host crash) or gain privileges on the host via vectors involving maptrack free list handling. Xenserver, Debian_linux, Xen 7.8
2018-05-08 CVE-2018-8897 A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs),... Mac_os_x, Ubuntu_linux, Xenserver, Debian_linux, Freebsd, Enterprise_linux_server, Enterprise_linux_workstation, Enterprise_virtualization_manager, Diskstation_manager, Skynas, Xen 7.8
2018-02-27 CVE-2018-7542 An issue was discovered in Xen 4.8.x through 4.10.x allowing x86 PVH guest OS users to cause a denial of service (NULL pointer dereference and hypervisor crash) by leveraging the mishandling of configurations that lack a Local APIC. Debian_linux, Xen 6.5
2018-02-27 CVE-2018-7541 An issue was discovered in Xen through 4.10.x allowing guest OS users to cause a denial of service (hypervisor crash) or gain privileges by triggering a grant-table transition from v2 to v1. Debian_linux, Xen 8.8
2018-02-27 CVE-2018-7540 An issue was discovered in Xen through 4.10.x allowing x86 PV guest OS users to cause a denial of service (host OS CPU hang) via non-preemptable L3/L4 pagetable freeing. Debian_linux, Xen 6.5
2018-01-05 CVE-2018-5244 In Xen 4.10, new infrastructure was introduced as part of an overhaul to how MSR emulation happens for guests. Unfortunately, one tracking structure isn't freed when a vcpu is destroyed. This allows guest OS administrators to cause a denial of service (host OS memory consumption) by rebooting many times. Xen 6.5
2018-12-08 CVE-2018-19967 An issue was discovered in Xen through 4.11.x on Intel x86 platforms allowing guest OS users to cause a denial of service (host OS hang) because Xen does not work around Intel's mishandling of certain HLE transactions associated with the KACQUIRE instruction prefix. Debian_linux, Xen 6.5
2018-12-08 CVE-2018-19963 An issue was discovered in Xen 4.11 allowing HVM guest OS users to cause a denial of service (host OS crash) or possibly gain host OS privileges because x86 IOREQ server resource accounting (for external emulators) was mishandled. Xen 7.8
