CVE-2022-49508
7.8
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
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).
