The vulnerability of the set_memory_region_test function (arch/x86/kvm/svm/svm.c) in Linux operating system kernels allows a malicious actor to cause a service failure.

The vulnerability of the setmemoryregiontest function arch/x86/kvm/svm/svm.c in Linux operating systems is related to an infinite loop. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2020-36311

An issue was discovered in the Linux kernel before 5.9. arch/x86/kvm/svm/sev.c allows attackers to cause a denial of service soft lockup by triggering destruction of a large SEV VM which requires unregistering many encrypted regions, aka CID-7be74942f184...

UBUNTU-CVE-2021-29657

arch/x86/kvm/svm/nested.c in the Linux kernel before 5.11.12 has a use-after-free in which an AMD KVM guest can bypass access control on host OS MSRs when there are nested guests, aka CID-a58d9166a756. This occurs because of a TOCTOU race condition associated with a VMCB12 double fetch in...
