Description
In the Linux kernel, the following vulnerability has been resolved:
HID: elan: Fix potential double free in elan_input_configured
'input' is a managed resource allocated with devm_input_allocate_device(),
so there is no need to call input_free_device() explicitly or
there will be a double free.
According to the doc of devm_input_allocate_device():
* Managed input devices do not need to be explicitly unregistered or
* freed as it will be done automatically when owner device unbinds from
* its driver (or binding fails).
Affected configurations
• linux linux kernel (>= 4.17 < 4.19.247)
• linux linux kernel (>= 4.20 < 5.4.198)
• linux linux kernel (>= 5.5 < 5.10.121)
• linux linux kernel (>= 5.11 < 5.15.46)
