Linux Kernel SCSI lpfc Memory Allocation Error Vulnerability

A vulnerability in the Linux kernel's SCSI lpfc driver has been addressed. The issue arose in the function lpfc_sli4_cgn_params_read(), where the failure of the memory allocation function kzalloc() was not properly handled. Instead of returning an appropriate error code, the function relied on lpfc_read_object() to check for null pointers, which could lead to a null pointer dereference. The original error code of -ENODEV has been changed to -ENOMEM to reflect the memory allocation error more accurately.

Impact

The vulnerability could potentially lead to improper error handling and memory management, causing confusion in the error reporting process.
