KVM SVM Buffer Overflow DoS

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...
