In the Linux kernel, the following vulnerability has been resolved:

irqchip/gic-v3-its: Prevent leak in its_vpe_irq_domain_alloc()

When its_irq_gic_domain_alloc() fails, the following
its_vpe_irq_domain_free() fails to invoke its_vep_teardown() for the
corresponding interrupt, which leaks the resource.

Invoke its_vpe_teardown() in the error handling path to avoid the leak.
