In Mbed TLS 3.2.0 though 3.6.6 and 4.0.0 through 4.1.0, an attacker who can cause an entropy source to fail can remove or inject bytes into the start of the TLS stream. This only affects TLS 1.3 servers.

CVE-2026-34874 2 Mbed-tls, Trustedfirmware 2 Mbedtls, Mbed Tls 2026-06-05 7.5 High
An issue was discovered in Mbed TLS through 3.6.5 and 4.x through 4.0.0. There is a NULL pointer dereference in distinguished name parsing that allows an attacker to write to address 0.
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-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-2024-23744 1 Trustedfirmware 1 Mbed Tls 2026-06-05 7.5 High
An issue was discovered in Mbed TLS 3.5.1. There is persistent handshake denial if a client sends a TLS 1.3 ClientHello without extensions.
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-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-2023-45199 2 Mbed, Trustedfirmware 2 Mbedtls, Mbed Tls 2026-06-05 9.8 Critical
Mbed TLS 3.2.x through 3.4.x before 3.5 has a Buffer Overflow that can lead to remote Code execution.
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-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-2024-23775 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-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-2024-45158 2 Mbed, Trustedfirmware 2 Mbedtls, Mbed Tls 2026-06-05 9.8 Critical
An issue was discovered in Mbed TLS 3.6 before 3.6.1. A stack buffer overflow in mbedtls_ecdsa_der_to_raw() and mbedtls_ecdsa_raw_to_der() can occur when the bits parameter is larger than the largest supported curve. In some configurations with PSA disabled, all values of bits are affected. (This never happens in internal library calls, but can affect applications that call these functions directly.)
CVE-2025-49087 2 Mbed, Trustedfirmware 2 Mbedtls, Mbed Tls 2026-06-05 4 Medium
In Mbed TLS 3.6.1 through 3.6.3 before 3.6.4, a timing discrepancy in block cipher padding removal allows an attacker to recover the plaintext when PKCS#7 padding mode is used.
CVE-2024-28960 4 Arm, Fedoraproject, Mbed and 1 more 6 Mbed Crypto, Mbed Tls, Fedora and 3 more 2026-06-05 8.2 High
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.
