Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak issue has been identified in the Linux kernel, specifically in the wfx init common() function.

To address this, an error label has been added to unify the error handler, which will be useful for subsequent changes.
