CVE-2026-34873 2 Mbed-tls, Trustedfirmware 2 Mbedtls, Mbed Tls 2026-06-05 9.1 Critical
An issue was discovered in Mbed TLS 3.5.0 through 4.0.0. Client impersonation can occur while resuming a TLS 1.3 session.
CVE-2021-45450 2 Fedoraproject, Trustedfirmware 2 Fedora, Mbed Tls 2026-06-05 7.5 High
In Mbed TLS before 2.28.0 and 3.x before 3.1.0, psa_cipher_generate_iv and psa_cipher_encrypt allow policy bypass or oracle-based decryption when the output buffer is at memory locations accessible to an untrusted application.
CVE-2025-49600 2 Mbed, Trustedfirmware 2 Mbedtls, Mbed Tls 2026-06-05 4.9 Medium
In MbedTLS 3.3.0 before 3.6.4, mbedtls_lms_verify may accept invalid signatures if hash computation fails and internal errors go unchecked, enabling LMS (Leighton-Micali Signature) forgery in a fault scenario. Specifically, unchecked return values in mbedtls_lms_verify allow an attacker (who can induce a hardware hash accelerator fault) to bypass LMS signature verification by reusing stale stack data, resulting in acceptance of an invalid signature. In mbedtls_lms_verify, the return values of the internal Merkle tree functions create_merkle_leaf_value and create_merkle_internal_value are not checked. These functions return an integer that indicates whether the call succeeded or not. If a failure occurs, the output buffer (Tc_candidate_root_node) may remain uninitialized, and the result of the signature verification is unpredictable. When the software implementation of SHA-256 is used, these functions will not fail. However, with hardware-accelerated hashing, an attacker could use fault injection against the accelerator to bypass verification.
CVE-2024-28755 2 Mbed, Trustedfirmware 2 Mbedtls, Mbed Tls 2026-06-05 6.5 Medium
An issue was discovered in Mbed TLS 3.5.x before 3.6.0. When an SSL context was reset with the mbedtls_ssl_session_reset() API, the maximum TLS version to be negotiated was not restored to the configured one. An attacker was able to prevent an Mbed TLS server from establishing any TLS 1.3 connection, potentially resulting in a Denial of Service or forced version downgrade from TLS 1.3 to TLS 1.2.
CVE-2024-45157 1 Trustedfirmware 1 Mbed Tls 2026-06-05 5.1 Medium
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 MBEDTLS_PSA_HMAC_DRBG_MD_TYPE does not cause the PSA subsystem to use HMAC_DRBG: it uses HMAC_DRBG only when MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG and MBEDTLS_CTR_DRBG_C are disabled.
CVE-2025-27809 2 Arm, Trustedfirmware 2 Mbed Tls, Mbed Tls 2026-06-05 5.4 Medium
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.
CVE-2026-25834 2 Mbed-tls, Trustedfirmware 2 Mbedtls, Mbed Tls 2026-06-05 6.5 Medium
Mbed TLS v3.3.0 up to 3.6.5 and 4.0.0 allows Algorithm Downgrade.
CVE-2017-2784 1 Trustedfirmware 1 Mbed Tls 2026-06-05 N/A
An exploitable free of a stack pointer vulnerability exists in the x509 certificate parsing code of ARM mbed TLS before 1.3.19, 2.x before 2.1.7, and 2.4.x before 2.4.2. A specially crafted x509 certificate, when parsed by mbed TLS library, can cause an invalid free of a stack pointer leading to a potential remote code execution. In order to exploit this vulnerability, an attacker can act as either a client or a server on a network to deliver malicious x509 certificates to vulnerable applications.
CVE-2026-34877 3 Arm, Mbed, Trustedfirmware 3 Mbed Tls, Mbedtls, Mbed Tls 2026-06-05 9.8 Critical
An issue was discovered in Mbed TLS versions from 2.19.0 up to 3.6.5, Mbed TLS 4.0.0. Insufficient protection of serialized SSL context or session structures allows an attacker who can modify the serialized structures to induce memory corruption, leading to arbitrary code execution. This is caused by Incorrect Use of Privileged APIs.
CVE-2018-19608 2 Arm, Trustedfirmware 2 Mbed Tls, Mbed Tls 2026-06-05 N/A
Arm Mbed TLS before 2.14.1, before 2.7.8, and before 2.1.17 allows a local unprivileged attacker to recover the plaintext of RSA decryption, which is used in RSA-without-(EC)DH(E) cipher suites.
CVE-2026-25833 2 Mbed-tls, Trustedfirmware 2 Mbedtls, Mbed Tls 2026-06-05 7.5 High
Mbed TLS 3.5.0 to 3.6.5 fixed in 3.6.6 and 4.1.0 has a buffer overflow in the x509_inet_pton_ipv6() function
CVE-2024-28836 1 Trustedfirmware 1 Mbed Tls 2026-06-05 5.4 Medium
An issue was discovered in Mbed TLS 3.5.x before 3.6.0. When negotiating the TLS version on the server side, it can fall back to the TLS 1.2 implementation of the protocol if it is disabled. If the TLS 1.2 implementation was disabled at build time, a TLS 1.2 client could put a TLS 1.3-only server into an infinite loop processing a TLS 1.2 ClientHello, resulting in a denial of service. If the TLS 1.2 implementation was disabled at runtime, a TLS 1.2 client can successfully establish a TLS 1.2 connection with the server.
CVE-2024-49195 2 Mbed, Trustedfirmware 2 Mbedtls, Mbed Tls 2026-06-05 9.8 Critical
Mbed TLS 3.5.x through 3.6.x before 3.6.2 has a buffer underrun in pkwrite when writing an opaque key pair
CVE-2017-14032 2 Arm, Trustedfirmware 2 Mbed Tls, Mbed Tls 2026-06-05 N/A
ARM mbed TLS before 1.3.21 and 2.x before 2.1.9, if optional authentication is configured, allows remote attackers to bypass peer authentication via an X.509 certificate chain with many intermediates. NOTE: although mbed TLS was formerly known as PolarSSL, the releases shipped with the PolarSSL name are not affected.
CVE-2022-46392 3 Arm, Fedoraproject, Trustedfirmware 3 Mbed Tls, Fedora, Mbed Tls 2026-06-05 5.3 Medium
An issue was discovered in Mbed TLS before 2.28.2 and 3.x before 3.3.0. An adversary with access to precise enough information about memory accesses (typically, an untrusted operating system attacking a secure enclave) can recover an RSA private key after observing the victim performing a single private-key operation, if the window size (MBEDTLS_MPI_WINDOW_SIZE) used for the exponentiation is 3 or smaller.
CVE-2022-46393 3 Arm, Fedoraproject, Trustedfirmware 3 Mbed Tls, Fedora, Mbed Tls 2026-06-05 9.8 Critical
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.
CVE-2021-36647 2 Arm, Trustedfirmware 2 Mbed Tls, Mbed Tls 2026-06-05 4.7 Medium
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 such as SGX or the TrustZone secure world) to recover the private keys used in RSA.
CVE-2024-23170 2 Arm, Trustedfirmware 2 Mbed Tls, Mbed Tls 2026-06-05 5.5 Medium
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 "Everlasting ROBOT: the Marvin Attack" by Hubert Kario.
CVE-2024-23775 2 Arm, Trustedfirmware 2 Mbed Tls, Mbed Tls 2026-06-05 7.5 High
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().
CVE-2015-5291 5 Debian, Fedoraproject, Opensuse and 2 more 6 Debian Linux, Fedora, Leap and 3 more 2026-06-05 N/A
Heap-based buffer overflow in PolarSSL 1.x before 1.2.17 and ARM mbed TLS (formerly PolarSSL) 1.3.x before 1.3.14 and 2.x before 2.1.2 allows remote SSL servers to cause a denial of service (client crash) and possibly execute arbitrary code via a long hostname to the server name indication (SNI) extension, which is not properly handled when creating a ClientHello message. NOTE: this identifier has been SPLIT per ADT3 due to different affected version ranges. See CVE-2015-8036 for the session ticket issue that was introduced in 1.3.0.
