AI-suggested
A fix is available in the Linux kernel source as indicated by the fixed commit versions. Users should update to a Linux kernel version that includes these fixes to resolve the reference count leak in mpi3mr_sas_port_add().
Description
A reference count leak vulnerability was fixed in the Linux kernel's mpi3mr driver in version 6.1. The issue occurs in the mpi3mr_sas_port_add() function where a target device reference is incremented but not properly released on error paths, causing the target device structure to never be freed.
