What fixes it

  • 2fd6ecda5d1f47cffcfadddb35ee49402162c724LinuxCVE List

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

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.
