Overview

CVE-2022-50337 is a medium-severity vulnerability. It was published on September 15, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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:

ocxl: fix pci device refcount leak when calling get_function_0()

get_function_0() calls pci_get_domain_bus_and_slot(), as comment

says, it returns a pci device with refcount increment, so after

using it, pci_dev_put() needs be called.

Get the device reference when get_function_0() is not called, so

pci_dev_put() can be called in the error path and callers

unconditionally. And add comment above get_dvsec_vendor0() to tell

callers to call pci_dev_put().

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.
