## Overview

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

eth: bnxt: fix missing ring index trim on error path

Commit under Fixes converted tx_prod to be free running but missed
masking it on the Tx error path. This crashes on error conditions,
for example when DMA mapping fails.

## Affected

- `linux_kernel >= 6.8, < 6.12.25`
- `linux_kernel >= 6.13, < 6.14.4`
- `linux_kernel = 6.15`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.14.4`
