{"id":"CVE-2024-31143","details":"An optional feature of PCI MSI called \"Multiple Message\" allows a\ndevice to use multiple consecutive interrupt vectors.  Unlike for MSI-X,\nthe setting up of these consecutive vectors needs to happen all in one\ngo.  In this handling an error path could be taken in different\nsituations, with or without a particular lock held.
