Overview

CVE-2026-98128 is a medium-severity vulnerability affecting linux linux_kernel. It was published on September 25, 2026 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: mpi3mr: Fix target device refcount leak in mpi3mr_sas_port_add()

mpi3mr_get_tgtdev_by_addr() increments the target device kref when it

returns a device. If a subsequent error triggers a goto out_fail after

the tgtdev reference is acquired, the reference is never released

because the out_fail path does not call mpi3mr_tgtdev_put(). This

prevents the target device structure from ever being freed.

Add a tgtdev put in the out_fail path, guarded by a NULL check since

tgtdev is only acquired for SAS_END_DEVICE types and the same cleanup

path is shared by earlier error cases where tgtdev is still NULL.

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.
