| + | Mitigation | ||
| + | As an alternate less invasive countermeasure, the affected cipher modes chacha20-poly1305 and any encrypt-then-mac variants (generic EtM) may be (temporarily) disabled. Some cipher modes, in particular AES-GCM, are not affected and can still be used without changes. | ||
| + | |||
| + | You can disable the following ciphers and HMACs as a workaround on RHEL-8 and RHEL-9: | ||
