CVE-2021-26334
CVE-2021-26334 affects AMD μProf Tool via the AMDPowerProfiler.sys driver. The root cause is improper access control that could let a low-privilege user access MSRs in the kernel, enabling privilege escalation and potential ring-0 code execution. Affected product: AMD μProf (AMDuProf). Exploitati...

kernel: KVM: double fetch in nested_svm_vmrun can lead to unrestricted MSR access
A flaw was found in the Linux kernel. A KVM guest on AMD can launch a nested guest without the Intercept VMRUN control bit by exploiting a TOCTOU vulnerability in nestedsvmvmrun. A malicious guest could use this flaw to gain unrestricted access to host MSRs, possibly leading to guest-to-host esca...

Race condition
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...
CVE-2021-29657
CVE-2021-29657 affects the Linux kernel KVM SVM nested virtualization (AMD). A TOCTOU race in arch/x86/kvm/svm/nested.c/nested_svm_vmrun allows a guest to bypass interception checks and corrupt the saved L1 host context, potentially enabling a guest-to-host influence over host MSR state via neste...
