Jul 04, 2025 cve

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.
