Vulnerability from cvelistv5 – Published: 2026-09-03 08:21 – Updated: 2026-09-03 08:21

Title

ata: pata_sl82c105: fix bridge revision use-after-free

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.

GHSA-P564-MWRX-5M7J

Vulnerability from github – Published: 2026-09-03 15:32 – Updated: 2026-09-03 15:32

Details

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.
