Description

An issue was discovered in the Linux kernel before 5.8. arch/x86/kvm/svm/svm.c allows a set_memory_region_test infinite loop for certain nested page faults, aka CID-e72436bc3a52. A flaw was found in the Linux kernel. A nested page fault is created when an address does not have a memslot associated to it. The highest threat from this vulnerability is to system availability. This flaw can be triggered using a malformed Virtual Machine. When triggered this bug will lead to the user-space component of KVM to freeze.
