pmdomain: core: Fix detach procedure for virtual devices in genpd
Overview
Description
In the Linux kernel, the following vulnerability has been resolved: pmdomain: core: Fix detach procedure for virtual devices in genpd If a device is attached to a PM domain through genpd_dev_pm_attach_by_id(), genpd calls pm_runtime_enable() for the corresponding virtual device that it registers. While this avoids boilerplate code in drivers, there is no corresponding call to pm_runtime_disable() in genpd_dev_pm_detach(). This means these virtual devices are typically detached from its genpd, while runtime PM remains enabled for them, which is not how things are designed to work. In worst cases it may lead to critical errors, like a NULL pointer dereference bug in genpd_runtime_suspend(), which was recently reported. For another case, we may end up keeping an unnecessary vote for a performance state for the device. To fix these problems, let's add this missing call to pm_runtime_disable() in genpd_dev_pm_detach().

Solution
Fix detach procedure for virtual devices by adding a missing runtime PM disable call.
- Ensure pm_runtime_disable() is called in genpd_dev_pm_detach().
- Apply the patch to the Linux kernel.
- Update the Linux kernel to the fixed version.

Action Type Old Value New Value Added Translation Title: Linux, Description: En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: pmdomain: core: Soluciona el procedimiento de desvinculación para dispositivos virtuales en genpd Si un dispositivo se adjunta a un dominio de PM a través de genpd_dev_pm_attach_by_id(), genpd llama a pm_runtime_enable() para el dispositivo virtual correspondiente que registra. Si bien esto evita código repetitivo en los controladores, no hay una llamada correspondiente a pm_runtime_disable() en genpd_dev_pm_detach(). Esto significa que estos dispositivos virtuales suelen desvincularse de su genpd, mientras que el PM en tiempo de ejecución permanece habilitado para ellos, lo cual no es como las cosas están diseñadas para funcionar. En los peores casos puede llevar a errores críticos, como un error de desreferencia de puntero NULL en genpd_runtime_suspend(), el cual fue reportado recientemente. Para otro caso, podemos terminar manteniendo un voto innecesario para un estado de rendimiento para el dispositivo. Para solucionar estos problemas, agreguemos esta llamada faltante a pm_runtime_disable() en genpd_dev_pm_detach(). -
