Title
scsi: mpt3sas: Fix possible resource leaks in mpt3sas_transport_port_add()
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: mpt3sas: Fix possible resource leaks in mpt3sas_transport_port_add()
In mpt3sas_transport_port_add(), if sas_rphy_add() returns error,
sas_rphy_free() needs be called to free the resource allocated in
sas_end_device_alloc(). Otherwise a kernel crash will happen:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000108
CPU: 45 PID: 37020 Comm: bash Kdump: loaded Tainted: G W 6.1.0-rc1+ #189
pstate: 60000005 (nZCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--)
pc : device_del+0x54/0x3d0
lr : device_del+0x37c/0x3d0

sas_remove_host+0x20/0x38 [scsi_transport_sas]
scsih_remove+0xd8/0x420 [mpt3sas]
Because transport_add_device() is not called when sas_rphy_add() fails, the
device is not added. When sas_rphy_remove() is subsequently called to
remove the device in the remove() path, a NULL pointer dereference happens.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
