However, transport drivers\nare fully registered and operational even if the physical RMI driver\nfailed to bind or probe the rmi_dev device.\n\nWhen rmi_driver_suspend() or rmi_driver_resume() is called on an unbound\nrmi_dev, dev_get_drvdata() returns NULL. Calling rmi_disable_irq() or\nrmi_enable_irq() without driver data attached causes a NULL pointer\ndereference and General Protection Fault when attempting to lock\ndata->enabled_mutex.\n\nFix this by checking if driver data is attached to rmi_dev in\nrmi_driver_suspend() and rmi_driver_resume(), exiting early if\nno driver data is present.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/30366f507ce3e408caf7f7375bb343df54b9a4f9","tags":[]},{"url":"https://git.kernel.org/stable/c/7a3d7c68aa36f68e2a4824da4782c0e5d7c4eba4","tags":[]},{"url":"https://git.kernel.org/stable/c/84145a4a1dc58f8959811913c5f61f3235dd9f6c","tags":[]},{"url":"https://git.kernel.org/stable/c/942b06a19252908d0f952c0590caf20e47f88252","tags":[]},{"url":"https://git.kernel.org/stable/c/e2b6703465c1ce43edb91c1626604b7092b3c431","tags":[]},{"url":"https://git.kernel.org/stable/c/fa1713dc3d43d028d6cb66e5659d9d7e83b73362","tags":[]},{"url":"https://git.kernel.org/stable/c/fafca210631d8c2d4311bdfccc5ec46b9fe65977","tags":[]},{"url":"https://git.kernel.org/stable/c/fe10579b6dc3f0dac61e51e1797cacbba5039ac2","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
