CVE-2022-46487

Estado: ModificadaAlta (7.8)—

Improper initialization of x87 and SSE floating-point configuration registers in the __scone_entry component of SCONE before 5.8.0 for Intel SGX allows a local attacker to compromise the execution integrity of floating-point operations in an enclave or access sensitive information via side-channel analysis.
