| Subject: CVE-2024-35897: netfilter: nf_tables: discard table flag update with pending basechain deletion |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| netfilter: nf_tables: discard table flag update with pending basechain deletion |
| |
| Hook unregistration is deferred to the commit phase, same occurs with |
| hook updates triggered by the table dormant flag. When both commands are |
| combined, this results in deleting a basechain while leaving its hook |
| still registered in the core. |
| |
| The Linux kernel CVE team has assigned CVE-2024-35897 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: |
