Vulnerability from cvelistv5

Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
An optional feature of PCI MSI called "Multiple Message" allows a device to use multiple consecutive interrupt vectors. Unlike for MSI-X, the setting up of these consecutive vectors needs to happen all in one go. In this handling an error path could be taken in different situations, with or without a particular lock held. This error path wrongly releases the lock even when it is not currently held.
