## Description

Redis before 8.8.0, in the unusual case where an authenticated attacker can execute RESTORE, allows remote code execution via a RESTORE payload where the same NACK (pending entry) is referenced by more than one consumer, because deleting both consumers via XGROUP DELCONSUMER leads to a double free. NOTE: this issue exists because of an incomplete fix for CVE-2026-25243.
