| Subject: CVE-2022-48966: net: mvneta: Prevent out of bounds read in mvneta_config_rss() |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: mvneta: Prevent out of bounds read in mvneta_config_rss() |
| |
| The pp->indir[0] value comes from the user. It is passed to: |
| |
| if (cpu_online(pp->rxq_def)) |
| |
| inside the mvneta_percpu_elect() function. It needs bounds checkeding |
| to ensure that it is not beyond the end of the cpu bitmap. |
| |
| The Linux kernel CVE team has assigned CVE-2022-48966 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: |
