Описание
A flaw was found in KVM. An improper check in svm_set_x2apic_msr_interception() may allow direct access to host x2apic msrs when the guest resets its apic, potentially leading to a denial of service condition.
Отчет
Red Hat Enterprise Linux 6 and 7 are not affected by this CVE as they did not include support for (de)activating x2AVIC mode, introduced upstream in kernel v6.0 with commit 4d1d794.
Меры по смягчению последствий
