| Subject: CVE-2022-48693: soc: brcmstb: pm-arm: Fix refcount leak and __iomem leak bugs |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| soc: brcmstb: pm-arm: Fix refcount leak and __iomem leak bugs |
| |
| In brcmstb_pm_probe(), there are two kinds of leak bugs: |
| |
| (1) we need to add of_node_put() when for_each__matching_node() breaks |
| (2) we need to add iounmap() for each iomap in fail path |
| |
| The Linux kernel CVE team has assigned CVE-2022-48693 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: |
