An issue was discovered in Mbed TLS before 2.24.0 and before 2.16.8 LTS and before 2.7.17 LTS. There is missing zeroization of plaintext buffers in mbedtlssslread to erase unused application data from memory...

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...

In Trusted Firmware Mbed TLS 2.24.0, a side-channel vulnerability in base64 PEM file decoding allows system-level administrator attackers to obtain information about secret RSA keys via a controlled-channel and side-channel attack on software running in isolated environments that can be single...

JLSEC-2025-206 An issue was discovered in Arm Mbed TLS before 2.23.0

An issue was discovered in Arm Mbed TLS before 2.23.0. A remote attacker can recover plaintext because a certain Lucky 13 countermeasure doesn't properly consider the case of a hardware accelerator...

JLSEC-2025-232 Side channel in RSA key generation and operations (SSBleed, M-Step)

Vulnerability Mbed TLS's modular inversion routine and GCD routine are vulnerable to local timing attacks in a number of settings discussed below. These functions are used in RSA, making the following operations vulnerable in all configurations: - RSA key generation with any API mbedtlsrsagenkey...

JLSEC-2025-207 An issue was discovered in Arm Mbed TLS before 2.24.0

An issue was discovered in Arm Mbed TLS before 2.24.0. An attacker can recover a private key for RSA or static Diffie-Hellman via a side-channel attack against generation of base blinding/unblinding values...

JLSEC-2025-218 An issue was discovered in Mbed TLS before 2.28.1 and 3.x before 3.2.0

An issue was discovered in Mbed TLS before 2.28.1 and 3.x before 3.2.0. In some configurations, an unauthenticated attacker can send an invalid ClientHello message to a DTLS server that causes a heap-based buffer over-read of up to 255 bytes. This can cause a server crash or possibly information...
