Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 4.13.3
Description
The issue allows guest OS users to cause a denial of service, leading to an assertion failure, and potentially causing the hypervisor to hang or crash. This is related to an out-of-bounds
guest irq value in the KVM subsystem, specifically in the files arch/x86/kvm/vmx.c and virt/kvm/eventfd.c.Recommendations
For Linux kernel versions prior to 4.13.3, update to version 4.13.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the KVM subsystem to minimize the risk of exploitation.
