JLSEC-2025-223 An issue was discovered in Mbed TLS 2.x before 2.28.7 and 3.x before 3.5.2

An issue was discovered in Mbed TLS 2.x before 2.28.7 and 3.x before 3.5.2. There was a timing side channel in RSA private operations. This side channel could be sufficient for a local attacker to recover the plaintext. It requires the attacker to send a large number of messages for decryption, a...

JLSEC-2025-226 An issue was discovered in Mbed TLS before 2.28.9 and 3.x before 3.6.1, in which the user-selected...

An issue was discovered in Mbed TLS before 2.28.9 and 3.x before 3.6.1, in which the user-selected algorithm is not used. Unlike previously documented, enabling MBEDTLSPSAHMACDRBGMDTYPE does not cause the PSA subsystem to use HMACDRBG: it uses HMACDRBG only when MBEDTLSPSACRYPTOEXTERNALRNG and...

JLSEC-2025-210 An issue was discovered in Mbed TLS before 2.25.0 (and before 2.16.9 LTS and before 2.7.18 LTS)

An issue was discovered in Mbed TLS before 2.25.0 and before 2.16.9 LTS and before 2.7.18 LTS. The calculations performed by mbedtlsmpiexpmod are not limited; thus, supplying overly large parameters could lead to denial of service when generating Diffie-Hellman key pairs...
