CVE-2025-1713

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.

Al configurar la reasignación de interrupciones para dispositivos PCI(-X) antiguos, incluidos los puentes PCI(-X), se requiere una búsqueda del puente ascendente. Esta búsqueda, que implica la adquisición de un bloqueo, se realiza en un contexto donde la adquisición de dicho bloqueo no es segura. Esto puede provocar un interbloqueo.
