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.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.

Attack Technique

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
