CVE-2022-46392 Information

Description

An issue was discovered in Mbed TLS before 2.28.2 and 3.x before 3.3.0. An adversary with access to precise enough information about memory accesses (typically an untrusted operating system attacking a secure enclave) can recover an RSA private key after observing the victim performing a single private-key operation if the window size (MBEDTLS_MPI_WINDOW_SIZE) used for the exponentiation is 3 or smaller.
