| Subject: CVE-2022-49354: ata: pata_octeon_cf: Fix refcount leak in octeon_cf_probe |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| ata: pata_octeon_cf: Fix refcount leak in octeon_cf_probe |
| |
| of_find_device_by_node() takes reference, we should use put_device() |
| to release it when not need anymore. |
| Add missing put_device() to avoid refcount leak. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49354 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: |
