CVE-2026-64105

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 kvmvgicvcpudestroy() call to the kvmsharehyp() failure path in kvmarchvcpucreate(). The kvmvgicvcpu_init() failure path immediately above it has the same shape and still needs the same cleanup.

Call kvmvgicvcpudestroy() when kvmvgicvcpuinit() fails so private IRQs allocated before a redistributor iodev registration failure are released before the failed vCPU is freed.
