 Redis Enterprise Software 7.22.0-28 supports open source Redis 7.4, 7.2, and 6.2. Below is the list of open source Redis CVEs fixed by version.
 
+Redis 7.4.x:
+
+- (CVE-2025-21605) An unauthenticated client can cause unlimited growth of output buffers until the server runs out of memory or is terminated, which can lead to denial-of-service.

 Redis 7.2.x:
 
+- (CVE-2025-21605) An unauthenticated client can cause unlimited growth of output buffers until the server runs out of memory or is terminated, which can lead to denial-of-service.
+
 - (CVE-2024-31449) An authenticated user may use a specially crafted Lua script to trigger a stack buffer overflow in the bit library, which may potentially lead to remote code execution.
 
 - (CVE-2024-31228) An authenticated user can trigger a denial-of-service by using specially crafted, long string match patterns on supported commands such as `KEYS`, `SCAN`, `PSUBSCRIBE`, `FUNCTION LIST`, `COMMAND LIST`, and ACL definitions. Matching of extremely long patterns may result in unbounded recursion, leading to stack overflow and process crashes.
