CVE-2025-1713

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

CVSS 7.5 HIGHEPSS 0.7%CWE-833

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.
