Overview

CVE-2025-23151 is a high-severity vulnerability. It was published on May 1, 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:

bus: mhi: host: Fix race between unprepare and queue_buf

A client driver may use mhi_unprepare_from_transfer() to quiesce

incoming data during the client driver's tear down. The client driver

might also be processing data at the same time, resulting in a call to

mhi_queue_buf() which will invoke mhi_gen_tre(). If mhi_gen_tre() runs

after mhi_unprepare_from_transfer() has torn down the channel, a panic

will occur due to an invalid dereference leading to a page fault.

This occurs because mhi_gen_tre() does not verify the channel state

after locking it. Fix this by having mhi_gen_tre() confirm the channel

state is valid, or return error to avoid accessing deinitialized data.

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.
