How to fix?

Upgrade SLES:15.6 openssl-3 to version 3.1.4-150600.5.18.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream openssl-3 package and not the openssl-3 package as distributed by SLES. See How to fix? for SLES:15.6 relevant fixed versions and status.

Validating the order of the public keys in the Diffie-Hellman Key Agreement Protocol, when an approved safe prime is used, allows remote attackers (from the client side) to trigger unnecessarily expensive server-side DHE modular-exponentiation calculations. The client may cause asymmetric resource consumption. The basic attack scenario is that the client must claim that it can only communicate with DHE, and the server must be configured to allow DHE and validate the order of the public key.
