Overview

CVE-2023-53175 is a medium-severity vulnerability. It was published on September 15, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

Technical description

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

PCI: hv: Fix a crash in hv_pci_restore_msi_msg() during hibernation

When a Linux VM with an assigned PCI device runs on Hyper-V, if the PCI

device driver is not loaded yet (i.e. MSI-X/MSI is not enabled on the

device yet), doing a VM hibernation triggers a panic in

hv_pci_restore_msi_msg() -> msi_lock_descs(&pdev->dev), because

pdev->dev.msi.data is still NULL.

Avoid the panic by checking if MSI-X/MSI is enabled.

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.
