In the Linux kernel, the following vulnerability has been resolved:
extcon: Modify extcon device to be created after driver data is set
Currently, someone can invoke the sysfs such as state_show() intermittently before dev_set_drvdata() is done. And it can be a cause of kernel Oops because of edev is Null at that time. So modified the driver registration to after setting drviver data.
- Oops's backtrace.
