Vulnerability from fkie_nvd - Published: 2024-10-21 20:15 - Updated: 2026-06-17 05:16

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: amd8111: Fix PCI device reference count leak for_each_pci_dev() is implemented by pci_get_device(). The comment of pci_get_device() says that it will increase the reference count for the returned pci_dev and also decrease the reference count for the input pci_dev @from if it is not NULL. If we break for_each_pci_dev() loop with pdev not NULL, we need to call pci_dev_put() to decrease the reference count. Add the missing pci_dev_put() after the 'out' label. Since pci_dev_put() can handle NULL input parameter, there is no problem for the 'Device not found' branch. For the normal path, add pci_dev_put() in amd_gpio_exit().

The comment of\npci_get_device() says that it will increase the reference count for the\nreturned pci_dev and also decrease the reference count for the input\npci_dev @from if it is not NULL.\n\nIf we break for_each_pci_dev() loop with pdev not NULL, we need to call\npci_dev_put() to decrease the reference count. Add the missing\npci_dev_put() after the \u0027out\u0027 label. Since pci_dev_put() can handle NULL\ninput parameter, there is no problem for the \u0027Device not found\u0027 branch.\nFor the normal path, add pci_dev_put() in amd_gpio_exit()."

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.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
