FKIE_CVE-2026-89599
Vulnerability from fkie_nvd - Published: 2026-09-11 20:19 - Updated: 2026-09-14 13:19
Severity
Summary
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.
