CVE-2021-47008
CVE-2021-47008 relates to the Linux kernel KVM/SVM path where GHCB is updated in SIPI handling and MSR operations. The vulnerability arises if SIPIs occur without a corresponding AP Reset Hold, risking a NULL pointer dereference when GHCB is not mapped, and similarly a potential GHCB access issue...

The vulnerability of the svm_set_x2apic_msr_interception() function in the arch/x86/kvm/svm/svm.c module of the KVM subsystem in the Linux operating system allows a hacker to cause a service failure.
The vulnerability of the svmsetx2apicmsrinterception function in the arch/x86/kvm/svm/svm.c module of the KVM subsystem in the Linux operating system is related to an incorrect sequence of operations when switching to the xapic working mode. Exploiting this vulnerability could allow a attacker to...
