RLSA-2025:12008

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 Stack Buffer Overflow (CVE-2025-27151)

• redis: Redis Unauthenticated Denial of Service (CVE-2025-48367)
