CVE-2025-37828
5.5 · MEDIUMOverview
CVE-2025-37828 is a medium-severity vulnerability affecting linux linux_kernel. 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 and patches from linux. Update linux_kernel to the latest patched version. 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.
