Overview

CVE-2023-53037 is a high-severity vulnerability. It was published on May 2, 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: mpi3mr: Bad drive in topology results kernel crash

When the SAS Transport Layer support is enabled and a device exposed to

the OS by the driver fails INQUIRY commands, the driver frees up the memory

allocated for an internal HBA port data structure. However, in some places,

the reference to the freed memory is not cleared. When the firmware sends

the Device Info change event for the same device again, the freed memory is

accessed and that leads to memory corruption and OS crash.

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.
