Title
irqchip/gic-v3-its: Fix potential VPE leak on error
Summary
In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v3-its: Fix potential VPE leak on error
In its_vpe_irq_domain_alloc, when its_vpe_init() returns an error,
there is an off-by-one in the number of VPEs to be freed.
Fix it by simply passing the number of VPEs allocated, which is the
index of the loop iterating over the VPEs.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
