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. [ tglx: Massaged change log ]
