Vulnerability from github – Published: 2024-12-27 15:31 – Updated: 2025-01-14 15:30

Details

In the Linux kernel, the following vulnerability has been resolved:

PCI: endpoint: Fix PCI domain ID release in pci_epc_destroy()

pci_epc_destroy() invokes pci_bus_release_domain_nr() to release the PCI domain ID, but there are two issues:

'epc->dev' is passed to pci_bus_release_domain_nr() which was already freed by device_unregister(), leading to a use-after-free issue.
Domain ID corresponds to the EPC device parent, so passing 'epc->dev' is also wrong.

Fix these issues by passing 'epc->dev.parent' to pci_bus_release_domain_nr() and also do it before device_unregister().

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.
