| CVE-2026-34871 | MEDIO6.7 | An issue was discovered in Mbed TLS before 3.6.6 and 4.x before 4.1.0 and TF-PSA-Crypto before 1.1.0. There is a Predictable Seed in a Pseudo-Random Number Generator (PRNG). | 01/04/2026 |
| CVE-2026-25835 | ALTO7.7 | Mbed TLS before 3.6.6 and TF-PSA-Crypto before 1.1.0 misuse seeds in a Pseudo-Random Number Generator (PRNG). | 01/04/2026 |
| CVE-2025-59438 | MEDIO5.3 | Mbed TLS through 3.6.4 has an Observable Timing Discrepancy. | 21/10/2025 |
| CVE-2025-54764 | MEDIO6.2 | Mbed TLS before 3.6.5 allows a local timing attack against certain RSA operations, and direct calls to mbedtls_mpi_mod_inv or mbedtls_mpi_gcd. | 20/10/2025 |
| CVE-2025-47917 | CRÍTICO9.8 | Mbed TLS before 3.6.4 allows a use-after-free in certain situations of applications that are developed in accordance with the documentation. The function mbedtls_x509_string_to_names() takes a head argument that is documented as an output argument. The documentation does not suggest that the function will free that poi | 20/07/2025 |
| CVE-2025-48965 | ALTO7.5 | Mbed TLS before 3.6.4 has a NULL pointer dereference because mbedtls_asn1_store_named_data can trigger conflicting data with val.p of NULL but val.len greater than zero. | 20/07/2025 |
| CVE-2025-52497 | MEDIO4.8 | Mbed TLS before 3.6.4 has a PEM parsing one-byte heap-based buffer underflow, in mbedtls_pem_read_buffer and two mbedtls_pk_parse functions, via untrusted PEM input. | 04/07/2025 |
| CVE-2025-52496 | ALTO7.8 | Mbed TLS before 3.6.4 has a race condition in AESNI detection if certain compiler optimizations occur. An attacker may be able to extract an AES key from a multithreaded program, or perform a GCM forgery. | 04/07/2025 |
| CVE-2025-27810 | MEDIO4.8 | Mbed TLS before 2.28.10 and 3.x before 3.6.3, in some cases of failed memory allocation or hardware errors, uses uninitialized stack memory to compose the TLS Finished message, potentially leading to authentication bypasses such as replays. | 25/03/2025 |
| CVE-2025-27809 | MEDIO5.4 | Mbed TLS before 2.28.10 and 3.x before 3.6.3, on the client side, accepts servers that have trusted certificates for arbitrary hostnames unless the TLS client application calls mbedtls_ssl_set_hostname. | 25/03/2025 |
| CVE-2024-28960 | ALTO8.2 | An issue was discovered in Mbed TLS 2.18.0 through 2.28.x before 2.28.8 and 3.x before 3.6.0, and Mbed Crypto. The PSA Crypto API mishandles shared memory. | 29/03/2024 |
| CVE-2024-23775 | ALTO7.5 | Integer Overflow vulnerability in Mbed TLS 2.x before 2.28.7 and 3.x before 3.5.2, allows attackers to cause a denial of service (DoS) via mbedtls_x509_set_extension(). | 31/01/2024 |
| CVE-2024-23170 | MEDIO5.5 | 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, as described in "Everlas | 31/01/2024 |
| CVE-2023-52353 | ALTO7.5 | An issue was discovered in Mbed TLS through 3.5.1. In mbedtls_ssl_session_reset, the maximum negotiable TLS version is mishandled. For example, if the last connection negotiated TLS 1.2, then 1.2 becomes the new maximum. | 21/01/2024 |
| CVE-2023-43615 | ALTO7.5 | Mbed TLS 2.x before 2.28.5 and 3.x before 3.5.0 has a Buffer Overflow. | 07/10/2023 |
| CVE-2021-36647 | MEDIO4.7 | Use of a Broken or Risky Cryptographic Algorithm in the function mbedtls_mpi_exp_mod() in lignum.c in Mbed TLS Mbed TLS all versions before 3.0.0, 2.27.0 or 2.16.11 allows attackers with access to precise enough timing and memory access information (typically an untrusted operating system attacking a secure enclave suc | 17/01/2023 |
| CVE-2022-46393 | CRÍTICO9.8 | An issue was discovered in Mbed TLS before 2.28.2 and 3.x before 3.3.0. There is a potential heap-based buffer overflow and heap-based buffer over-read in DTLS if MBEDTLS_SSL_DTLS_CONNECTION_ID is enabled and MBEDTLS_SSL_CID_IN_LEN_MAX > 2 * MBEDTLS_SSL_CID_OUT_LEN_MAX. | 15/12/2022 |
