Overview

CVE-2026-98129 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 NULL pointer dereference in mpi3mr_sas_port_add()

sas_port_alloc_num() can return NULL on memory allocation failure. The

return value is passed directly to sas_port_add() without a NULL check,

which causes a NULL pointer dereference.

Additionally, if sas_port_add() fails, the allocated port is not freed

before jumping to out_fail, leaking the sas_port structure. Call

sas_port_free() to properly release it.

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.
