CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's KVM (Kernel-based Virtual Machine) component, specifically in the ARM64 architecture, where private IRQs may not be properly freed during the failure of vCPU initialization. This oversight can lead to resource leaks, potentially impacting system stability and performance. Organizations utilizing KVM on ARM64 systems should prioritize addressing this issue to ensure optimal resource management and prevent potential disruptions.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic: Free private_irqs when init fails after allocation Companion to commit 250f25367b58 ("KVM: arm64: Tear down vGIC on failed vCPU creation"), which added the missing kvm_vgic_vcpu_destroy() call to the kvm_share_hyp() failure path in kvm_arch_vcpu_create(). The kvm_vgic_vcpu_init() failure path immediately above it has the same shape and still needs the same cleanup. Call kvm_vgic_vcpu_destroy() when kvm_vgic_vcpu_init() fails so private IRQs allocated before a redistributor iodev registration failure are released before the failed vCPU is freed.
