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.
