Overview

CVE-2025-37828 is a medium-severity vulnerability. It was published on May 8, 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:

scsi: ufs: mcq: Add NULL check in ufshcd_mcq_abort()

A race can occur between the MCQ completion path and the abort handler:

once a request completes, __blk_mq_free_request() sets rq->mq_hctx to

NULL, meaning the subsequent ufshcd_mcq_req_to_hwq() call in

ufshcd_mcq_abort() can return a NULL pointer. If this NULL pointer is

dereferenced, the kernel will crash.

Add a NULL check for the returned hwq pointer. If hwq is NULL, log an

error and return FAILED, preventing a potential NULL-pointer

dereference. As suggested by Bart, the ufshcd_cmd_inflight() check is

removed.

This is similar to the fix in commit 74736103fb41 ("scsi: ufs: core: Fix

ufshcd_abort_one racing issue").

This is found by our static analysis tool KNighter.

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.
