| Subject: CVE-2023-52532: net: mana: Fix TX CQE error handling |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: mana: Fix TX CQE error handling |
| |
| For an unknown TX CQE error type (probably from a newer hardware), |
| still free the SKB, update the queue tail, etc., otherwise the |
| accounting will be wrong. |
| |
| Also, TX errors can be triggered by injecting corrupted packets, so |
| replace the WARN_ONCE to ratelimited error logging. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52532 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: |
| https://git.kernel.org/stable/c/b67d7b1bfc46d05c1a58b172516454698e8d5004 |
