| Subject: CVE-2022-49188: remoteproc: qcom_q6v5_mss: Fix some leaks in q6v5_alloc_memory_region |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| remoteproc: qcom_q6v5_mss: Fix some leaks in q6v5_alloc_memory_region |
| |
| The device_node pointer is returned by of_parse_phandle() or |
| of_get_child_by_name() with refcount incremented. |
| We should use of_node_put() on it when done. |
| |
| This function only call of_node_put(node) when of_address_to_resource |
| succeeds, missing error cases. |
| |
| The Linux kernel CVE team has assigned CVE-2022-49188 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: |
