In the Linux kernel, the following vulnerability has been resolved:

fbdev: omapfb: panel-dsi-cm: initialize lock before registering display

dsicm_probe() registers the display before initializing ddata->lock.

Once omapdss_register_display() publishes the display, another consumer

can reach a dsicm callback that takes this mutex while it is still

uninitialized.

Initialize the mutex before registering the display so the published

callbacks always see a valid lock. (NVD)
