Description

In the Linux kernel, the following vulnerability has been resolved:

ALSA: ctxfi: Fix memory leakage when clearing DAO input mappers

Commit e576e7843c0d ("ALSA: ctxfi: Simplify dao_clear_{left,right}_input() functions") centralized the DAO input mapper clearing logic in dao_clear_input(), but omitted the kfree() calls.

It removes the mapper entries from the list and sets their pointers to NULL without freeing the allocated array. This leaks memory each time dao_clear_input() is called.

Store the base pointer of the allocation before clearing the mapper entries and free the array after removing entries from the list.
