SUSE CVE-2018-19966
An issue was discovered in Xen through 4.11.x allowing x86 PV guest OS users to cause a denial of service host OS crash or possibly gain host OS privileges because of an interpretation conflict for a union data structure associated with shadow paging. NOTE: this issue exists because of an incorre...
SUSE CVE-2020-15563
An issue was discovered in Xen through 4.13.x, allowing x86 HVM guest OS users to cause a hypervisor crash. An inverted conditional in x86 HVM guests' dirty video RAM tracking code allows such guests to make Xen de-reference a pointer guaranteed to point at unmapped space. A malicious or buggy HV...
SUSE CVE-2020-15567
An issue was discovered in Xen through 4.13.x, allowing Intel guest OS users to gain privileges or cause a denial of service because of non-atomic modification of a live EPT PTE. When mapping guest EPT nested paging tables, Xen would in some circumstances use a series of non-atomic bitfield write...
SUSE CVE-2021-28710
certain VT-d IOMMUs may not work in shared page table mode For efficiency reasons, address translation control structures page tables may and, on suitable hardware, by default will be shared between CPUs, for second-level translation EPT, and IOMMUs. These page tables are presently set up to alwa...
SUSE CVE-2021-38198
arch/x86/kvm/mmu/pagingtmpl.h in the Linux kernel before 5.12.11 incorrectly computes the access permissions of a shadow page, leading to a missing guest protection page fault...
SUSE CVE-2022-1789
With shadow paging enabled, the INVPCID instruction results in a call to kvmmmuinvpcidgva. If INVPCID is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference...
