CVE-2024-31143
CVSS v3.1
7.5
High
| Vector | AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue concerns an optional feature of PCI MSI called "Multiple Message" that 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.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
Improper Locking
