| Subject: CVE-2022-49442: drivers/base/node.c: fix compaction sysfs file leak |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| drivers/base/node.c: fix compaction sysfs file leak |
| |
| Compaction sysfs file is created via compaction_register_node in |
| register_node. But we forgot to remove it in unregister_node. Thus |
| compaction sysfs file is leaked. Using compaction_unregister_node to fix |
| this issue. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49442 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: |
