Description
In the Linux kernel, the following vulnerability has been resolved:
backlight: pm8941: Add NULL check in wled_configure()
devm_kasprintf() returns NULL when memory allocation fails. Currently,
wled_configure() does not check for this case, which results in a NULL
pointer dereference.
Add NULL check after devm_kasprintf() to prevent this issue.
