Description
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.
Affected configurations
• linux linux kernel (>= 5.15 < 5.15.34)
• linux linux kernel (>= 5.16 < 5.16.20)
• linux linux kernel (>= 5.17 < 5.17.3)
