## Overview

In the Linux kernel, the following vulnerability has been resolved:

bnxt_en: Fix null pointer dereference in bnxt_bs_trace_check_wrap()

With older FW, we may get the ASYNC_EVENT_CMPL_EVENT_ID_DBG_BUF_PRODUCER
for FW trace data type that has not been initialized.  This will result
in a crash in bnxt_bs_trace_type_wrap().  Add a guard to check for a
valid magic_byte pointer before proceeding.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
