CVE-2024-43821 Information

Description

In the Linux kernel the following vulnerability has been resolved:

scsi: lpfc: Fix a possible null pointer dereference

In function lpfc_xcvr_data_show the memory allocation with kmalloc might fail thereby making rdp_context a null pointer. In the following context and functions that use this pointer there are dereferencing operations leading to null pointer dereference.

To fix this issue a null pointer check should be added. If it is null use scnprintf to notify the user and return len.
