| Subject: CVE-2024-53164: net: sched: fix ordering of qlen adjustment |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| net: sched: fix ordering of qlen adjustment |
| |
| Changes to sch->q.qlen around qdisc_tree_reduce_backlog() need to happen |
| _before_ a call to said function because otherwise it may fail to notify |
| parent qdiscs when the child is about to become empty. |
| |
| The Linux kernel CVE team has assigned CVE-2024-53164 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: |
