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...
PT-2026-26327
Two buffer overflow vulnerabilities existed in the wolfSSL CRL parser when parsing CRL numbers: a heap-based buffer overflow could occur when improperly storing the CRL number as a hexadecimal string, and a stack-based overflow for sufficiently sized CRL numbers. With appropriately crafted CRLs,...

Name of the Vulnerable Software and Affected Versions wolfSSL version 5.8.4 Description The software contains a flaw in the constant-time masking logic within the sp 256 get entry 256 9 function. When compiled with GCC targeting RISC-V RV32I using the -O3 optimization flag, the logic is altered...
curl: Certificate Pinning Bypass with wolfSSL backend over HTTP/3
Summary: A security feature bypass exists in libcurl when built with the wolfSSL backend and HTTP/3 support. The Certificate Pinning feature --pinnedpubkey is silently ignored if the user also disables peer verification -k or --insecure . This behavior is inconsistent with other backends like...

Linux Distros Unpatched Vulnerability : CVE-2025-13912
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Multiple constant-time implementations in wolfSSL before version 5.8.4 may be transformed into non- constant-time binary by LLVM optimizations, which can...
PT-2025-50637
Name of the Vulnerable Software and Affected Versions wolfSSL versions prior to 5.8.4 Description Certain constant-time implementations within wolfSSL may be altered by LLVM optimizations into non-constant-time binaries. This transformation can introduce observable timing discrepancies, potential...
curl: Stack Buffer Overflow in cURL wolfSSL Backend (lib/vtls/wolfssl.c)
Summary: A stack-based buffer overflow exists in the wsslstrerror function of cURL's wolfSSL TLS backend. The function uses an unsafe strcpy call, relying solely on a DEBUGASSERT macro for boundary checking. This macro is disabled in production release builds -DNDEBUG, allowing memory corruption...
FreeBSD : wolfssl -- multiple issues (ba02dfb6-ce31-11f0-a327-589cfc01894a)
The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the ba02dfb6-ce31-11f0-a327-589cfc01894a advisory. wolfSSL blog reports: This release includes multiple fixes across TLS 1.2, TLS 1.3, X25519,...
