| Subject: CVE-2023-52571: power: supply: rk817: Fix node refcount leak |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| power: supply: rk817: Fix node refcount leak |
| |
| Dan Carpenter reports that the Smatch static checker warning has found |
| that there is another refcount leak in the probe function. While |
| of_node_put() was added in one of the return paths, it should in |
| fact be added for ALL return paths that return an error and at driver |
| removal time. |
| |
| The Linux kernel CVE team has assigned CVE-2023-52571 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: |
