Executive Summary

This vulnerability in Mbed TLS versions before 3.6.5 allows a local attacker to perform a timing attack on certain RSA operations and on direct calls to specific mathematical functions (mbedtls_mpi_mod_inv or mbedtls_mpi_gcd). This means an attacker could potentially gain sensitive information by measuring the time taken to perform these cryptographic operations.

Impact Analysis

The vulnerability could allow a local attacker to extract sensitive cryptographic information by analyzing timing differences during RSA operations, potentially compromising the security of encrypted data or cryptographic keys.
