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

mfd: cros_ec: Delay dev_set_drvdata() until probe success

If ec_device_probe() fails, cros_ec_class_release releases memory for the cros_ec_dev structure. However, because the drvdata was already set, sub-drivers like cros_ec_typec can still retrieve the stale pointer via the platform device. This leads to a use-after-free when cros_ec_typec attempts to access &typec->ec->ec->dev on a device that has already been released. Move dev_set_drvdata() to ensure that the pointer is only made available once all initialization steps have succeeded.
