| Subject: CVE-2024-35975: octeontx2-pf: Fix transmit scheduler resource leak |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| octeontx2-pf: Fix transmit scheduler resource leak |
| |
| Inorder to support shaping and scheduling, Upon class creation |
| Netdev driver allocates trasmit schedulers. |
| |
| The previous patch which added support for Round robin scheduling has |
| a bug due to which driver is not freeing transmit schedulers post |
| class deletion. |
| |
| This patch fixes the same. |
| |
| The Linux kernel CVE team has assigned CVE-2024-35975 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: |
