CVE-2026-98527 - Vulnerability Details

- gpio: zynq: fix runtime PM leak on request error path

Description

In the Linux kernel, the following vulnerability has been resolved:

gpio: zynq: fix runtime PM leak on request error path

pm_runtime_get_sync() leaves the usage counter incremented even when it
fails, and zynq_gpio_request() returns the error without dropping it.

gpiolib does not call ->free() when ->request() fails, so zynq_gpio_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.
