  "details": "In the Linux kernel, the following vulnerability has been resolved:  i3c: Fix unlocked dereference of dev-\u003edesc in i3c_device_get_supported_xfer_mode()  i3c_device_get_supported_xfer_mode() uses dev-\u003edesc to obtain the master controller.  However, dev-\u003edesc must not be dereferenced unless bus-\u003elock is held, and this function does not take that lock.  The function only needs access to the master controller associated with the device's bus.  Use dev-\u003ebus instead, which is always valid for the lifetime of the device and does not require dereferencing dev-\u003edesc.",
