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.
