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.
Affected configurations
• linux linux kernel (>= 6.2 < 6.6.44)
• linux linux kernel (>= 6.7 < 6.10.3)
