Overview

CVE-2026-80732 is a high-severity vulnerability. It was published on September 3, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
