Overview

CVE-2025-37861 is a high-severity vulnerability. It was published on May 9, 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: Synchronous access b/w reset and tm thread for reply queue

When the task management thread processes reply queues while the reset

thread resets them, the task management thread accesses an invalid queue ID

(0xFFFF), set by the reset thread, which points to unallocated memory,

causing a crash.

Add flag 'io_admin_reset_sync' to synchronize access between the reset,

I/O, and admin threads. Before a reset, the reset handler sets this flag to

block I/O and admin processing threads. If any thread bypasses the initial

check, the reset thread waits up to 10 seconds for processing to finish. If

the wait exceeds 10 seconds, the controller is marked as unrecoverable.

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.

How can CyberStrike help with CVE-2025-37861?

CyberStrike is an open-source, AI-augmented pentesting engine.
