Description OSIDB Bzimport 2025-02-26 03:06:42 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/panel: ili9341: fix optional regulator handling

If the optional regulator lookup fails, reset the pointer to NULL.
Other functions such as mipi_dbi_poweron_reset_conditional() only do
a NULL pointer check and will otherwise dereference the error pointer.
