Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，已修复以下漏洞： scsi: mpi3mr: 修复 mpi3mr_sas_port_add() 中目标设备引用计数泄漏问题 当 返回一个设备时，它会增加目标设备的 kref（内核引用计数）。如果在获取 tgtdev 引用后，后续发生错误并触发跳转到 标签，由于 路径未调用 ，导致该引用从未被释放。这将导致目标设备结构体永远无法被释放，从而引发内存泄漏。 在 路径中添加对 tgtdev 的 put 操作，并在使用前加上 NULL 检查。因为 tgtdev 仅在设备类型为 SAS_END_DEV

Vulnerability Title
scsi: mpi3mr: Fix target device refcount leak in mpi3mr_sas_port_add()
Source: CVE Program / CVE List V5
Vulnerability 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.
