  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: zynq: fix runtime PM leak on request error path\n\npm_runtime_get_sync() leaves the usage counter incremented even when it\nfails, and zynq_gpio_request() returns the error without dropping it.\n\ngpiolib does not call ->free() when ->request() fails, so zynq_gpio_free(),\nwhich holds the only matching pm_runtime_put(), never runs. The reference\nis leaked and the controller can no longer runtime-suspend, so its clock\nstays enabled.\n\nSwitch to pm_runtime_resume_and_get(), which only increments the usage\ncounter on success.",
