A Lucky 13 timing side channel in mbedtlsssldecryptbuf in library/sslmsg.c in Trusted Firmware Mbed TLS through 2.23.0 allows an attacker to recover secret key information. This affects CBC mode because of a computed time difference based on a padding length...

JLSEC-2025-233 Padding oracle through timing of cipher error reporting

Vulnerability In symmetric encryption modes that involve padding, if an attacker can submit ciphertexts for decryption and learn whether the padding is valid, this provides partial information about the plaintext. If the attacker can also submit input that the victim encrypts together with a...

An issue was discovered in Arm Mbed TLS before 2.23.0. A side channel allows recovery of an ECC private key, related to mbedtls ecp check pub priv, mbedtls pk parse key, mbedtls pk parse keyfile, mbedtls ecp mul, and mbedtls ecp mul restartable...

PT-2025-48508

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 mbedtls mpi exp mod are not limited; thus, supplying overly large parameters could lead to denial of service when generating Diffie-Hellman key pairs...

PT-2025-48510

An issue was discovered in Mbed TLS before 2.24.0. The verification of X.509 certificates when matching the expected common name the cn argument of mbedtls x509 crt verify with the actual certificate name is mishandled: when the subjecAltName extension is present, the expected name is compared to...

TencentOS Server 4: mbedtls (TSSA-2025:0337)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0337 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities...

Siemens SIMATIC S7-1500 Improper Validation of Certificate with Host Mismatch (CVE-2024-2466)

libcurl did not check the server certificate of TLS connections done to a host specified as an IP address, when built to use mbedTLS. libcurl would wrongly avoid using the set hostname function when the specified hostname was given as an IP address, therefore completely skipping the certificate...

CVE-2025-64429

DuckDB 1.4.0–pre-1.4.2 encryption implementation is vulnerable due to multiple cryptographic weaknesses: insecure RNG (pcg32 fallback), possible memory wipe omission (memset) leaving secrets, and header manipulation could downgrade from GCM to CTR, bypassing integrity. There may also be unhandled...
