Manuel Pégourié-Gonnard reports:

An attacker with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave such as SGX or the TrustZone secure world) can recover the private keys used in RSA or static (finite-field) Diffie-Hellman operations.
