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...

Windows Exploitation Tricks: Trapping Virtual Memory Access

Posted by James Forshaw, Project Zero This blog is a continuation of my series of Windows exploitation tricks. This one describes an exploitation trick I’ve been trying to develop for years, succeeding mostly, more on that later on the latest versions of Windows 10. It’s a trick to trap access to...
