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.
