| Subject: CVE-2024-57973: rdma/cxgb4: Prevent potential integer overflow on 32bit |
| |
| Description |
| =========== |
| |
| 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. |
| |
| The Linux kernel CVE team has assigned CVE-2024-57973 to this issue. |

| Mitigation |
| ========== |
| |
| The Linux kernel CVE team recommends that you update to the latest |
| stable kernel version for this, and many other bugfixes. Individual |
| changes are never tested alone, but rather are part of a larger kernel |
| release. Cherry-picking individual commits is not recommended or |
| supported by the Linux kernel community at all. If however, updating to |
| the latest release is impossible, the individual changes to resolve this |
| issue can be found at these commits: |
