Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： mailbox: imx: 使用 devm_pm_runtime_enable() Sashiko 报告称，在探针（probe）完成之前过早使用了该设备。可以通过将 pm_runtime_enable() 的调用推迟到移除路径中，而不是在早期执行，来缓解此问题。这样可以确保在发生错误时，设备会在调用 pm_runtime_disable() 之前先被移除（并执行 imx_mu_shutdown()），从而无需手动处理该过程。 为了使执行顺序正确，我们将 devm_mbo

Vulnerability Title
mailbox: imx: Use devm_pm_runtime_enable()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: mailbox: imx: Use devm_pm_runtime_enable() sashiko complained about early usage of the device while probe isn't completed. This can be mitigated by delaying the pm_runtime_enable() into the removal path instead doing it early. This ensures that in an error case the device is removed (and imx_mu_shutdown()) before pm_runtime_disable() so we don't have to do this manually. For the order to work, lets move devm_mbox_controller_register() until after the pm-runtime part. So the reverse order will be mbox-controller removal followed by disabling pm runtime. Use devm_pm_runtime_enable(), remove manual pm_runtime_disable() invocations and move the pm_runtime handling in probe before devm_mbox_controller_register().
