FKIE_CVE-2026-80732
Vulnerability from fkie_nvd - Published: 2026-09-03 13:06 - Updated: 2026-09-04 05:17
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
ata: pata_sl82c105: fix bridge revision use-after-free
pci_get_slot() returns a referenced PCI device. Commit 44c10138fd4b
("PCI: Change all drivers to use pci_device->revision") replaced a
configuration-space read with direct access to the cached revision field,
but left that access after pci_dev_put(). The bridge may therefore be freed
before its revision is read.
Read the revision before dropping the reference.

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.
