  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nfbdev: omapfb: panel-dsi-cm: initialize lock before registering display\n\ndsicm_probe() registers the display before initializing ddata->lock.\nOnce omapdss_register_display() publishes the display, another consumer\ncan reach a dsicm callback that takes this mutex while it is still\nuninitialized.\n\nInitialize the mutex before registering the display so the published\ncallbacks always see a valid lock.",
