## Overview

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

rdma/cxgb4: Prevent potential integer overflow on 32bit

The "gl->tot_len" variable is controlled by the user.  It comes from
process_responses().  On 32bit systems, the "gl->tot_len + sizeof(struct
cpl_pass_accept_req) + sizeof(struct rss_header)" addition could have an
integer wrapping bug.  Use size_add() to prevent this.

## Affected

- `linux_kernel >= 3.8, < 6.1.129`
- `linux_kernel >= 6.2, < 6.6.76`
- `linux_kernel >= 6.7, < 6.12.13`
- `linux_kernel >= 6.13, < 6.13.2`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.13.2`
