An information disclosure vulnerability exists in the Windows kernel that could allow an attacker to retrieve information that could lead to a Kernel Address Space Layout Randomization (ASLR) bypass. An attacker who successfully exploited the vulnerability could retrieve the memory address of a kernel object.
To exploit the vulnerability, an attacker would have to log on to an affected system and run a specially crafted application.
The security update addresses the vulnerability by correcting how the Windows kernel handles memory addresses.

CVE-2020-36310 [MEDIUM] CWE-835 kernel: infinite loop in set_memory_region_test in arch/x86/kvm/svm/svm.c for certain nested page faults
kernel: infinite loop in set_memory_region_test in arch/x86/kvm/svm/svm.c for certain nested page faults
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.
Statement: Red Hat Product Security does not consider this to be a vulnerability. This issue has addressed as a regular bug in the errata RHSA-2021:2185 and RHSA-2021:1578. T
