Security Advisories

For full details, please see the following links:

• CTR_DRBG prioritized over HMAC_DRBG as the PSA DRBG

Release Notes

Security

• Unlike previously documented, enabling MBEDTLS_PSA_HMAC_DRBG_MD_TYPE does
  not cause the PSA subsystem to use HMAC_DRBG: it uses HMAC_DRBG only when
  MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG and MBEDTLS_CTR_DRBG_C are disabled.
  CVE-2024-45157

Bugfix

• Fix the build in some configurations when check_config.h is not included.
  Fix #9152.
• Fix issue of redefinition warning messages for _GNU_SOURCE in
  entropy_poll.c and sha_256.c. There was a build warning during
  building for linux platform.
  Resolves #9026
• Fix error handling when creating a key in a dynamic secure element
  (feature enabled by MBEDTLS_PSA_CRYPTO_SE_C). In a low memory condition,
  the creation could return PSA_SUCCESS but using or destroying the key
  would not work. Fixes #8537.
• Fix a memory leak that could occur when failing to process an RSA
  key through some PSA functions due to low memory conditions.
• Document and enforce the limitation of mbedtls_psa_register_se_key()
  to persistent keys. Resolves #9253.
