Sources and claim methodology

Upstream source 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.
