Detail

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

s390/ism: add release function for struct device

According to device_release() in /drivers/base/core.c, a device without a release function is a broken device and must be fixed.

The current code directly frees the device after calling device_add() without waiting for other kernel parts to release their references. Thus, a reference could still be held to a struct device, e.g., by sysfs, leading to potential use-after-free issues if a proper release function is not set.
