CVE-2025-38576

powerpc/eeh: Make EEH driver device hotplug safe

Published Aug 19, 2025 CVSS 3.1 · 5.5 Medium EPSS < 1% KEV · Not listed
Description
In the Linux kernel, the following vulnerability has been resolved:

powerpc/eeh: Make EEH driver device hotplug safe

Multiple race conditions existed between the PCIe hotplug driver and the
EEH driver, leading to a variety of kernel oopses of the same general
nature:

<pcie device unplug>
<eeh driver trigger>
<hotplug removal trigger>
<pcie tree reconfiguration>
<eeh recovery next step>
<oops in EEH driver bus iteration loop>

A second class of oops is also seen when the underlying bus disappears
during device recovery.

Refactor the EEH module to be PCI rescan and remove safe. Also clean
up a few minor formatting / readability issues.
