SUSE CVE-2016-2270
Xen 4.6.x and earlier allows local guest administrators to cause a denial of service host reboot via vectors related to multiple mappings of MMIO pages with different cachability settings...
SUSE CVE-2016-9383
Xen, when running on a 64-bit hypervisor, allows local x86 guest OS users to modify arbitrary memory and consequently obtain sensitive information, cause a denial of service host crash, or execute arbitrary code on the host by leveraging broken emulation of bit test instructions...
SUSE CVE-2016-10025
VMFUNC emulation in Xen 4.6.x through 4.8.x on x86 systems using AMD virtualization extensions aka SVM allows local HVM guest OS users to cause a denial of service hypervisor crash by leveraging a missing NULL pointer check...
SUSE 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...
SUSE CVE-2019-17340
An issue was discovered in Xen through 4.11.x allowing x86 guest OS users to cause a denial of service or gain privileges because grant-table transfer requests are mishandled...
SUSE CVE-2019-17351
An issue was discovered in drivers/xen/balloon.c in the Linux kernel before 5.2.3, as used in Xen through 4.12.x, allowing guest OS users to cause a denial of service because of unrestricted resource consumption during the mapping of guest memory, aka CID-6ef36ab967c7...
SUSE CVE-2019-18421
An issue was discovered in Xen through 4.12.x allowing x86 PV guest OS users to gain host OS privileges by leveraging race conditions in pagetable promotion and demotion operations. There are issues with restartable PV type change operations. To avoid using shadow pagetables for PV guests, Xen...
SUSE CVE-2019-19583
An issue was discovered in Xen through 4.12.x allowing x86 HVM/PVH guest OS users to cause a denial of service guest OS crash because VMX VMEntry checks mishandle a certain case. Please see XSA-260 for background on the MovSS shadow. Please see XSA-156 for background on the need for DB...
SUSE CVE-2020-25598
An issue was discovered in Xen 4.14.x. There is a missing unlock in the XENMEMacquireresource error path. The RCU Read, Copy, Update mechanism is a synchronisation primitive. A buggy error path in the XENMEMacquireresource exits without releasing an RCU reference, which is conceptually similar to...
SUSE CVE-2020-27673
An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. Guest OS users can cause a denial of service host OS hang via a high rate of events to dom0, aka CID-e99502f76271...
SUSE CVE-2020-27675
An issue was discovered in the Linux kernel through 5.9.1, as used with Xen through 4.14.x. drivers/xen/events/eventsbase.c allows event-channel removal during the event-handling loop a race condition. This can cause a use-after-free or NULL pointer dereference, as demonstrated by a dom0 crash vi...
SUSE CVE-2021-26931
An issue was discovered in the Linux kernel 2.6.39 through 5.10.16, as used in Xen. Block, net, and SCSI backends consider certain errors a plain bug, deliberately causing a kernel crash. For errors potentially being at least under the influence of guests such as out of memory conditions, it isn'...
SUSE CVE-2021-27379
An issue was discovered in Xen through 4.11.x, allowing x86 Intel HVM guest OS users to achieve unintended read/write DMA access, and possibly cause a denial of service host OS crash or gain privileges. This occurs because a backport missed a flush, and thus IOMMU updates were not always correct...
SUSE CVE-2021-28039
An issue was discovered in the Linux kernel 5.9.x through 5.11.3, as used with Xen. In some less-common configurations, an x86 PV guest OS user can crash a Dom0 or driver domain via a large amount of I/O activity. The issue relates to misuse of guest physical addresses when a configuration has...
GSD-2022-1007537 xen/gntdev: Prevent leaking grants
xen/gntdev: Prevent leaking grants This is an automated ID intended to aid in discovery of potential security vulnerabilities. The actual impact and attack plausibility have not yet been proven. This ID is fixed in Linux Kernel version v4.19.264 by commit cb1ccfe7655380f77a58b340072f5f40bc285902,...
