| Subject: CVE-2024-39492: mailbox: mtk-cmdq: Fix pm_runtime_get_sync() warning in mbox shutdown |
| |
| Description |
| =========== |
| |
| In the Linux kernel, the following vulnerability has been resolved: |
| |
| mailbox: mtk-cmdq: Fix pm_runtime_get_sync() warning in mbox shutdown |
| |
| The return value of pm_runtime_get_sync() in cmdq_mbox_shutdown() |
| will return 1 when pm runtime state is active, and we don't want to |
| get the warning message in this case. |
| |
| So we change the return value < 0 for WARN_ON(). |
| |
| The Linux kernel CVE team has assigned CVE-2024-39492 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: |
| https://git.kernel.org/stable/c/2d42a37a4518478f075ccf848242b4a50e313a46 |
