CVE-2023-53124

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> scsi: mpt3sas: Fix NULL pointer access in mpt3sas_transport_port_add()<br /> <br /> Port is allocated by sas_port_alloc_num() and rphy is allocated by either<br /> sas_end_device_alloc() or sas_expander_alloc(), all of which may return<br /> NULL. So we need to check the rphy to avoid possible NULL pointer access.<br /> <br /> If sas_rphy_add() returned with failure, rphy is set to NULL. We would<br /> access the rphy in the following lines which would also result NULL pointer<br /> access.
