CVE-2021-28705

issues with partially successful P2M updates on x86 This CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE. x86 HVM and PVH guests may be started in populate-on-demand PoD mode, to provide a way for them to later easily have...

SUSE CVE-2018-12891

An issue was discovered in Xen through 4.10.x. Certain PV MMU operations may take a long time to process. For that reason Xen explicitly checks for the need to preempt the current vCPU at certain points. A few rarely taken code paths did bypass such checks. By suitably enforcing the conditions...

SUSE CVE-2019-17347

An issue was discovered in Xen through 4.11.x allowing x86 PV guest OS users to cause a denial of service or gain privileges because a guest can manipulate its virtualised %cr4 in a way that is incompatible with Linux and possibly other guest kernels...

SUSE CVE-2019-19582

An issue was discovered in Xen through 4.12.x allowing x86 guest OS users to cause a denial of service infinite loop because certain bit iteration is mishandled. In a number of places bitmaps are being used by the hypervisor to track certain state. Iteration over all bits involves functions which...

race in VT-d domain ID cleanup

ISSUE DESCRIPTION Xen domain IDs are up to 15 bits wide. VT-d hardware may allow for only less than 15 bits to hold a domain ID associating a physical device with a particular domain. Therefore internally Xen domain IDs are mapped to the smaller value range. The cleaning up of the housekeeping...

CVE-2022-23035

Insufficient cleanup of passed-through device IRQs The management of IRQs associated with physical devices exposed to x86 HVM guests involves an iterative operation in particular when cleaning up after the guest's use of the device. In the case where an interrupt is not quiescent yet at the time...
