# CVE-2026-80732

> 7.8 HIGH

## Beschreibung

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.
