CVE-2026-80732

HighCVSS 7.8/10Last modified Sep 4, 2026

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.
