CVE-2022-35977: Integer overflow in the Redis SETRANGE and SORT/SORT_RO commands may result with false OOM panic
Redis is an in-memory database that persists on disk.

The problem is fixed in Redis versions 7.0.8, 6.2.9 and 6.0.17. Users are advised to upgrade. There are no known workarounds for this vulnerability.
