CVE-2023-53663 KVM: nSVM: Check instead of asserting on nested TSC scaling support

In the Linux kernel, the following vulnerability has been resolved: KVM: nSVM: Check instead of asserting on nested TSC scaling support Check for nested TSC scaling support on nested SVM VMRUN instead of asserting that TSC scaling is exposed to L1 if L1's MSRAMD64TSCRATIO has diverged from KVM's...

CVE-2023-53663

CVE-2023-53663 concerns the Linux kernel KVM nSVM nested-VM path. The issue occurs when nested TSC scaling support is checked on nested SVM VMRUN and an MSR write together with a guest CPUID update hides the feature, causing the guest to trigger a WARN repeatedly (sequence shown) instead of a cor...
