Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
An issue exists in the KVM arm64 vgic component where
private irqs are not freed when initialization fails after allocation. Specifically, the failure path in kvm vgic vcpu init() lacks a call to kvm vgic vcpu destroy(), which prevents the release of private IRQs allocated before a redistributor iodev registration failure occurs during vCPU creation.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
