Summary
Important: redis security, bug fix, and enhancement update
Details

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:AlmaLinux-180910)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
