The vulnerability has been fixed in the Linux kernel by the referenced commits. Users should update their Linux kernel to a version that includes these fixes. No additional mitigation steps are required beyond applying the official patch.
Description
A vulnerability in the Linux kernel's input subsystem related to soc_button_array was fixed by adding a check to ensure btns_desc->package.count is not zero before accessing btns_desc->package.elements[0]. This prevents potential invalid memory access.
