This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

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

bnxt_en: Adjust logging of firmware messages in case of released token in __hwrm_send()

In case of token is released due to token->state == BNXT_HWRM_DEFERRED,

released token (set to NULL) is used in log messages. This issue is

expected to be prevented by HWRM_ERR_CODE_PF_UNAVAILABLE error code. But

this error code is returned by recent firmware. So some firmware may not

return it. This may lead to NULL pointer dereference.

Adjust this issue by adding token pointer check.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
