CVE-2026-98129 scsi: mpi3mr: Fix NULL pointer dereference in mpi3mr_sas_port_add()

What is CVE-2026-98129?

CVE-2026-98129 is a medium-severity vulnerability in Linux kernel, published on 25 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.

Official 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.

Weakness: CWE-476
