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