CVE-2026-64105 Details
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.
A vulnerability exists in the Linux kernel's KVM component for ARM64 architecture, specifically within the virtual Generic Interrupt Controller (vGIC) handling. The issue arises when the vGIC virtual CPU initialization fails after private interrupts have been allocated. In such cases, the allocated interrupts are not properly released before the failed virtual CPU is freed, potentially leading to resource leaks. This vulnerability affects the Linux kernel stable tree.
The vulnerability has been addressed in the Linux kernel. Users should upgrade to the latest version where this issue has been fixed.
