| Subject: CVE-2024-42154: tcp_metrics: validate source addr length |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| tcp_metrics: validate source addr length |
| |
| I don't see anything checking that TCP_METRICS_ATTR_SADDR_IPV4 |
| is at least 4 bytes long, and the policy doesn't have an entry |
| for this attribute at all (neither does it for IPv6 but v6 is |
| manually validated). |
| |
| The Linux kernel CVE team has assigned CVE-2024-42154 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: |
