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. The Linux kernel CVE team has assigned CVE-2026-98202 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/input/rmi4/rmi_driver.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/7a3d7c68aa36f68e2a4824da4782c0e5d7c4eba4 https://git.kernel.org/stable/c/fafca210631d8c2d4311bdfccc5ec46b9fe65977 https://git.kernel.org/stable/c/84145a4a1dc58f8959811913c5f61f3235dd9f6c https://git.kernel.org/stable/c/e2b6703465c1ce43edb91c1626604b7092b3c431 https://git.kernel.org/stable/c/30366f507ce3e408caf7f7375bb343df54b9a4f9 https://git.kernel.org/stable/c/fa1713dc3d43d028d6cb66e5659d9d7e83b73362 https://git.kernel.org/stable/c/942b06a19252908d0f952c0590caf20e47f88252 https://git.kernel.org/stable/c/fe10579b6dc3f0dac61e51e1797cacbba5039ac2
