Description

An issue was discovered in Fortanix EnclaveOS Confidential Computing Manager (CCM) Platform before 3.32 for Intel SGX. Lack of pointer-alignment validation logic in entry functions allows a local attacker to access unauthorized information. This relates to the enclave_ecall function and system call layer.
