JLSEC-2025-201 An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15

An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by 1 reconstructing the projective coordinate of the result of scalar multiplication by exploiting side...

The ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS through 2.19.1 does not reduce the blinded scalar before computing the inverse, which allows a local attacker to recover the private key via side-channel attacks...

JLSEC-2025-198 Arm Mbed TLS before 2.19.0 and Arm Mbed Crypto before 2.0.0, when deterministic ECDSA is enabled,...

Arm Mbed TLS before 2.19.0 and Arm Mbed Crypto before 2.0.0, when deterministic ECDSA is enabled, use an RNG with insufficient entropy for blinding, which might allow an attacker to recover a private key via side-channel attacks if a victim signs the same message many times. For Mbed TLS, the fix...

JLSEC-2025-205 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 side channel allows recovery of an ECC private key, related to mbedtlsecpcheckpubpriv, mbedtlspkparsekey, mbedtlspkparsekeyfile, mbedtlsecpmul, and mbedtlsecpmulrestartable...

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-2025-204 An issue was discovered in Arm Mbed TLS before 2.23.0

An issue was discovered in Arm Mbed TLS before 2.23.0. Because of a side channel in modular exponentiation, an RSA private key used in a secure enclave could be disclosed...

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-2025-207 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...
