CVE-2026-3849 (GCVE-0-2026-3849)
Vulnerability from cvelistv5 – Published: 2026-03-19 20:29 – Updated: 2026-03-25 14:21

Title
Buffer Overflow in HPKE via Oversized ECH Config
Summary
Stack Buffer Overflow in wc_HpkeLabeledExtract via Oversized ECH Config. A vulnerability existed in wolfSSL 5.8.4 ECH (Encrypted Client Hello) support, where a maliciously crafted ECH config could cause a stack buffer overflow on the client side, leading to potential remote execution and client program crash. This could be exploited by a malicious TLS server supporting ECH. Note that ECH is off by default, and is only enabled with enable-ech.

Title
Fault injection attack with ML-DSA and ML-KEM on ARM
Summary
Protection mechanism failure in wolfCrypt post-quantum implementations (ML-KEM and ML-DSA) in wolfSSL on ARM Cortex-M microcontrollers allows a physical attacker to compromise key material and/or cryptographic outcomes via induced transient faults that corrupt or redirect seed/pointer values during Keccak-based expansion.
This issue affects wolfSSL (wolfCrypt): commit hash d86575c766e6e67ef93545fa69c04d6eb49400c6.

CVE-2025-7844 (GCVE-0-2025-7844)
Vulnerability from cvelistv5 – Published: 2025-08-04 21:35 – Updated: 2025-08-05 13:36
VLAI
Title
wolfTPM library wrapper function `wolfTPM2_RsaKey_TpmToWolf` copies external data to a fixed-size stack buffer without length validation potentially causing stack-based buffer overflow
Summary
Exporting a TPM based RSA key larger than 2048 bits from the TPM could overrun a stack buffer if the default `MAX_RSA_KEY_BITS=2048` is used. If your TPM 2.0 module supports RSA key sizes larger than 2048 bit and your applications supports creating or importing an RSA private or public key larger than 2048 bits and your application calls `wolfTPM2_RsaKey_TpmToWolf` on that key, then a stack buffer could be overrun. If the `MAX_RSA_KEY_BITS` build-time macro is set correctly (RSA bits match what TPM hardware is capable of) for the hardware target, then a stack overrun is not possible.

CVE-2024-5288 (GCVE-0-2024-5288)
Vulnerability from cvelistv5 – Published: 2024-08-27 18:36 – Updated: 2024-08-27 19:23
VLAI
Title
Safe-error attack on TLS 1.3 Protocol
Summary
An issue was discovered in wolfSSL before 5.7.0. A safe-error attack via Rowhammer, namely FAULT+PROBE, leads to ECDSA key disclosure. When WOLFSSL_CHECK_SIG_FAULTS is used in signing operations with private ECC keys,
such as in server-side TLS connections, the connection is halted if any fault occurs. The success rate in a certain amount of connection requests can be processed via an advanced technique for ECDSA key recovery.
