Redis contains a use-after-free vulnerability in the 'tlsProcessPendingData()' function, which handles the TLS pending-data list if Redis is configured with TLS support. A remote, unauthenticated attacker may be able to execute arbitrary commands with the privileges of the Redis server.

    Redis is an advanced key-value store. It is often referred to as a data-structure server since keys can     contain strings, hashes, lists, sets, and sorted sets. For performance, Redis works with an in-memory data     set. You can persist it either by dumping the data set to disk every once in a while, or by appending each     command to a log.

    Security Fix(es):

    * redis: Redis: Remote Code Execution via specially crafted RESTORE payload (CVE-2026-66373)

    * redis: Redis: Arbitrary code execution via TLS pending-data list use-after-free (CVE-2026-81934)
