Vulnerability from fkie_nvd - Published: 2026-06-25 09:16 - Updated: 2026-07-18 16:17

Severity

5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: gpio: rockchip: fix generic IRQ chip leak on remove The driver allocates domain generic chips using irq_alloc_domain_generic_chips() during probe. However, on driver remove/teardown, the generic chips are not automatically freed when the IRQ domain is removed because the domain flags do not include IRQ_DOMAIN_FLAG_DESTROY_GC. This causes both the domain generic chips structure and the associated generic chips to be leaked. Additionally, the generic chips remain on the global gc_list and may later be visited by generic IRQ chip suspend, resume, or shutdown callbacks after the GPIO bank has been removed, potentially resulting in a use-after-free and kernel crash. Fix the resource leak by explicitly calling irq_domain_remove_generic_chips() before removing the IRQ domain in rockchip_gpio_remove().

However, on driver\nremove/teardown, the generic chips are not automatically freed when the\nIRQ domain is removed because the domain flags do not include\nIRQ_DOMAIN_FLAG_DESTROY_GC.\n\nThis causes both the domain generic chips structure and the associated\ngeneric chips to be leaked. Additionally, the generic chips remain on\nthe global gc_list and may later be visited by generic IRQ chip suspend,\nresume, or shutdown callbacks after the GPIO bank has been removed,\npotentially resulting in a use-after-free and kernel crash.\n\nFix the resource leak by explicitly calling\nirq_domain_remove_generic_chips() before removing the IRQ domain in\nrockchip_gpio_remove()."

Detection rules are retrieved from Rulezet.

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.
