deadlock potential with VT-d and legacy PCI device pass-through

Published Jul 17, 2025 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description
When setting up interrupt remapping for legacy PCI(-X) devices,
including PCI(-X) bridges, a lookup of the upstream bridge is required.
This lookup, itself involving acquiring of a lock, is done in a context
where acquiring that lock is unsafe. This can lead to a deadlock.
