| Subject: CVE-2024-35835: net/mlx5e: fix a double-free in arfs_create_groups |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net/mlx5e: fix a double-free in arfs_create_groups |
| |
| When `in` allocated by kvzalloc fails, arfs_create_groups will free |
| ft->g and return an error. However, arfs_create_table, the only caller of |
| arfs_create_groups, will hold this error and call to |
| mlx5e_destroy_flow_table, in which the ft->g will be freed again. |
| |
| The Linux kernel CVE team has assigned CVE-2024-35835 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: |
