AI-suggested

A fix is available that addresses the resource leak by ensuring proper cleanup in the error handling path. Users should apply the updated Linux kernel versions that include this patch to mitigate the issue.

Description

A resource leak vulnerability in the Linux kernel's irqchip/gic-v3-its component was resolved. The issue occurs when its_irq_gic_domain_alloc() fails, causing its_vpe_irq_domain_free() to skip invoking its_vpe_teardown(), resulting in a resource leak. The fix ensures its_vpe_teardown() is called in the error handling path to prevent this leak.
