- 8.4 HIGH — CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Description
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.
