FFDH key exchange lacks contributory-behaviour / peer-key validation, enabling protocol-level abuse. Found independently by Eva Crystal (0xiviel).
Out-of-bounds read in mbedtls_ccm_finish(): an oversized tag_len in the multipart CCM API exposes adjacent CCM context data. Discovered through the Intigriti Trusted Firmware program.
Possible buffer overflow in mbedtls_ecdh_calc_secret() when the output buffer is too small - up to remote code execution.
