CVE-2025-52497 2 Arm, Mbed 2 Mbed Tls, Mbedtls 2025-11-03 4.8 Medium
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.
CVE-2025-52496 2 Arm, Mbed 2 Mbed Tls, Mbedtls 2025-11-03 7.8 High
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.
CVE-2025-48965 2 Arm, Mbed 2 Mbed Tls, Mbedtls 2025-11-03 4 Medium
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.
CVE-2025-47917 2 Arm, Mbed 2 Mbed Tls, Mbedtls 2025-11-03 8.9 High
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 pointer; however, the function does call mbedtls_asn1_free_named_data_list() on that argument, which performs a deep free(). As a result, application code that uses this function (relying only on documented behavior) is likely to still hold pointers to the memory blocks that were freed, resulting in a high risk of use-after-free or double-free. In particular, the two sample programs x509/cert_write and x509/cert_req are affected (use-after-free if the san string contains more than one DN).
CVE-2021-36647 1 Arm 1 Mbed Tls 2025-11-03 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-2021-24119 3 Arm, Debian, Fedoraproject 3 Mbed Tls, Debian Linux, Fedora 2025-11-03 4.9 Medium
In Trusted Firmware Mbed TLS 2.24.0, a side-channel vulnerability in base64 PEM file decoding allows system-level (administrator) attackers to obtain information about secret RSA keys via a controlled-channel and side-channel attack on software running in isolated environments that can be single stepped, especially Intel SGX.
CVE-2025-54764 3 Arm, Mbed, Mbed-tls 3 Mbed Tls, Mbed, Mbedtls 2025-10-31 6.2 Medium
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.
CVE-2025-59438 3 Arm, Mbed, Mbed-tls 3 Mbed Tls, Mbed, Mbedtls 2025-10-23 5.3 Medium
Mbed TLS through 3.6.4 has an Observable Timing Discrepancy.
CVE-2024-48984 2 Arm, Mbed 2 Mbed Os, Mbed 2025-09-24 9.8 Critical
An issue was discovered in MBed OS 6.16.0. When parsing hci reports, the hci parsing software dynamically determines the length of a list of reports by reading a byte from an input stream. It then fetches the length of the first report, uses it to calculate the beginning of the second report, etc. In doing this, it tracks the largest report so it can later allocate a buffer that fits every individual report (but only one at a time). It does not, however, validate that these addresses are all contained within the buffer passed to hciEvtProcessLeExtAdvReport. It is then possible, though unlikely, that the buffer designated to hold the reports is allocated in such a way that one of these out-of-bounds length fields is contained within the new buffer. When the (n-1)th report is copied, it overwrites the length field of the nth report. This now corrupted length field is then used for a memcpy into the new buffer, which may lead to a buffer overflow.
CVE-2024-22905 1 Arm 2 Mbed-os, Mbed Os 2025-09-15 7.0 High
Buffer Overflow vulnerability in ARM mbed-os v.6.17.0 allows a remote attacker to execute arbitrary code via a crafted script to the hciTrSerialRxIncoming function.
CVE-2024-28836 1 Arm 1 Mbed Tls 2025-06-27 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-2024-30166 1 Arm 1 Mbed Tls 2025-06-27 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-2024-28755 1 Arm 1 Mbed Tls 2025-06-10 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-2024-23744 1 Arm 1 Mbed Tls 2025-06-04 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-2023-52353 1 Arm 1 Mbed Tls 2025-05-30 7.5 High
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.
CVE-2024-45158 2 Arm, Mbed 2 Mbed Tls, Mbedtls 2025-05-16 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 Arm, Mbed 2 Mbed Tls, Mbedtls 2025-05-06 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-2017-2784 1 Arm 1 Mbed Tls 2025-04-20 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-2021-27435 1 Arm 1 Mbed 2025-04-16 7.3 High
ARM mbed product Version 6.3.0 is vulnerable to integer wrap-around in malloc_wrapper function, which can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution.
CVE-2021-27433 1 Arm 1 Mbed Ualloc 2025-04-16 7.3 High
ARM mbed-ualloc memory library version 1.3.0 is vulnerable to integer wrap-around in function mbed_krbs, which can lead to arbitrary memory allocation, resulting in unexpected behavior such as a crash or a remote code injection/execution.
