Upgrade armmbed/mbedtls to version 2.28.9, 3.6.1 or higher.
Overview
Affected versions of this package are vulnerable to Missing Cryptographic Step due to the incorrectly documented algorithm selection mechanism. An attacker can bypass security restrictions by exploiting the misconfiguration in the cryptographic algorithm selection process.
Workaround
To use HMAC_DRBG as the pseudorandom generator in the PSA subsystem, make sure that the compile-time option MBEDTLS_CTR_DRBG_C is disabled.
