Technical description

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

ethtool: fail closed if we can't get max channel used in indirection tables

Commit 0d1b7d6c9274 ("bnxt: fix crashes when reducing ring count with

active RSS contexts") proves that allowing indirection table to contain

channels with out of bounds IDs may lead to crashes. Currently the

max channel check in the core gets skipped if driver can't fetch

the indirection table or when we can't allocate memory.

Both of those conditions should be extremely rare but if they do

happen we should try to be safe and fail the channel change.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. 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.
