Vulnerability Title
Input: synaptics-rmi4 - fix GPF in suspend and resume when unbound
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: Input: synaptics-rmi4 - fix GPF in suspend and resume when unbound Transport drivers (such as rmi_i2c and rmi_spi) invoke rmi_driver_suspend() and rmi_driver_resume() on their child rmi_dev device during system power management events. However, transport drivers are fully registered and operational even if the physical RMI driver failed to bind or probe the rmi_dev device. When rmi_driver_suspend() or rmi_driver_resume() is called on an unbound rmi_dev, dev_get_drvdata() returns NULL. Calling rmi_disable_irq() or rmi_enable_irq() without driver data attached causes a NULL pointer dereference and General Protection Fault when attempting to lock data->enabled_mutex. Fix this by checking if driver data is attached to rmi_dev in rmi_driver_suspend() and rmi_driver_resume(), exiting early if no driver data is present.
