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-2024-28836 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-2024-28960 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.
CVE-2024-30166 2 Arm, Trustedfirmware 2 Mbed Tls, Mbed Tls 2026-06-05 9.1 Critical
In Mbed TLS 3.3.0 through 3.5.2 before 3.6.0, a malicious client can cause information disclosure or a denial of service because of a stack buffer over-read (of less than 256 bytes) in a TLS 1.3 server via a TLS 3.1 ClientHello.
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-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-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-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-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-2021-44732 3 Arm, Debian, Trustedfirmware 3 Mbed Tls, Debian Linux, Mbed Tls 2026-06-05 9.8 Critical
Mbed TLS before 3.0.1 has a double free in certain out-of-memory conditions, as demonstrated by an mbedtls_ssl_set_session() failure.
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-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-2025-27810 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, 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.
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-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-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-2026-34874 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-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-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.
