Overview

CVE-2025-37886 is a high-severity vulnerability. It was published on May 9, 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:

pds_core: make wait_context part of q_info

Make the wait_context a full part of the q_info struct rather

than a stack variable that goes away after pdsc_adminq_post()

is done so that the context is still available after the wait

loop has given up.

There was a case where a slow development firmware caused

the adminq request to time out, but then later the FW finally

finished the request and sent the interrupt. The handler tried

to complete_all() the completion context that had been created

on the stack in pdsc_adminq_post() but no longer existed.

This caused bad pointer usage, kernel crashes, and much wailing

and gnashing of teeth.

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.
