Vulnerability from github – Published: 2024-05-01 06:31 – Updated: 2024-10-31 18:31

Details

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

pci_iounmap(): Fix MMIO mapping leak

The #ifdef ARCH_HAS_GENERIC_IOPORT_MAP accidentally also guards iounmap(), which means MMIO mappings are leaked.

Move the guard so we call iounmap() for MMIO mappings.

Severity

5.5 (Medium)

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.

Related by attack behaviour

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.
