Synopsis
Important: redis security, bug fix, and enhancement update
Description
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)
Bug Fix(es) and Enhancement(s):
* segfault because of Unsupported system page size (jemalloc) (JIRA:Rocky Linux-180910)
