Vulnerability Details : CVE-2023-52809
In the Linux kernel, the following vulnerability has been resolved:
scsi: libfc: Fix potential NULL pointer dereference in fc_lport_ptp_setup()
fc_lport_ptp_setup() did not check the return value of fc_rport_create()
which can return NULL and would cause a NULL pointer dereference. Address
this issue by checking return value of fc_rport_create() and log error
message on fc_rport_create() failed.
