          "details": "Deprioritize: exploitation requires physical, high‑complexity electromagnetic side‑channel measurement during ElGamal decryption, which is not feasible over networks and is inherently blocked in virtualized cloud VMs and restricted datacenter settings. The issue only applies if vulnerable versions are actually performing ElGamal decryption; systems not using ElGamal for decryption are unaffected. With no integrity or availability impact and such narrow, on‑hardware preconditions, the practical risk to managed enterprise servers is minimal.",
