Overview

CVE-2023-53387 is a high-severity vulnerability. It was published on September 18, 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:

scsi: ufs: core: Fix device management cmd timeout flow

In the UFS error handling flow, the host will send a device management cmd

(NOP OUT) to the device for link recovery. If this cmd times out and

clearing the doorbell fails, ufshcd_wait_for_dev_cmd() will do nothing and

return. hba->dev_cmd.complete struct is not set to NULL.

When this happens, if cmd has been completed by device, then we will call

complete() in __ufshcd_transfer_req_compl(). Because the complete struct is

allocated on the stack, the following crash will occur:

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.
