Overview

CVE-2025-22022 is a high-severity vulnerability. It was published on April 16, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

usb: xhci: Apply the link chain quirk on NEC isoc endpoints

Two clearly different specimens of NEC uPD720200 (one with start/stop

bug, one without) were seen to cause IOMMU faults after some Missed

Service Errors. Faulting address is immediately after a transfer ring

segment and patched dynamic debug messages revealed that the MSE was

received when waiting for a TD near the end of that segment:

[ 1.041954] xhci_hcd: Miss service interval error for slot 1 ep 2 expected TD DMA ffa08fe0

[ 1.042120] xhci_hcd: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0005 address=0xffa09000 flags=0x0000]

[ 1.042146] xhci_hcd: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x0005 address=0xffa09040 flags=0x0000]

It gets even funnier if the next page is a ring segment accessible to

the HC. Below, it reports MSE in segment at ff1e8000, plows through a

zero-filled page at ff1e9000 and starts reporting events for TRBs in

page at ff1ea000 eve

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.

How can CyberStrike help with CVE-2025-22022?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2025-22022 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
