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： gpio: xilinx：修复请求错误路径上的运行时电源管理（runtime PM）泄漏问题 pm_runtime_get_sync() 即使在调用失败时也会将使用计数器递增，而 xgpio_request() 在返回错误时并未将其递减。 由于 gpiolib 在 ->request() 失败时不会调用 ->free()，因此 xgpio_free()（其中包含唯一对应的 pm_runtime_put()）永远不会被执行。这导致引用计数泄漏，控制器无法再进行运行时挂起（

Vulnerability Title
gpio: xilinx: fix runtime PM leak on request error path
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: gpio: xilinx: fix runtime PM leak on request error path pm_runtime_get_sync() leaves the usage counter incremented even when it fails, and xgpio_request() returns the error without dropping it. gpiolib does not call ->free() when ->request() fails, so xgpio_free(), which holds the only matching pm_runtime_put(), never runs. The reference is leaked and the controller can no longer runtime-suspend, so its clock stays enabled. Switch to pm_runtime_resume_and_get(), which only increments the usage counter on success.
