| Subject: CVE-2024-56783: netfilter: nft_socket: remove WARN_ON_ONCE on maximum cgroup level |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| netfilter: nft_socket: remove WARN_ON_ONCE on maximum cgroup level |
| |
| cgroup maximum depth is INT_MAX by default, there is a cgroup toggle to |
| restrict this maximum depth to a more reasonable value not to harm |
| performance. Remove unnecessary WARN_ON_ONCE which is reachable from |
| userspace. |
| |
| The Linux kernel CVE team has assigned CVE-2024-56783 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: |
