PT-2026-26368

Heap-based buffer overflow in the KCAPI ECC code path of wc ecc import x963 ex in wolfSSL wolfcrypt allows a remote attacker to write attacker-controlled data past the bounds of the pubkey raw buffer via a crafted oversized EC public key point. The WOLFSSL KCAPI ECC code path copies the input to...

Linux Distros Unpatched Vulnerability : CVE-2026-3579

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - wolfSSL 5.8.4 on RISC-V RV32I architectures lacks a constant-time software implementation for 64-bit multiplication. The compiler-inserted muldi3 subroutine...

Out-of-bounds read in ALPN parsing due to incomplete validation. wolfSSL 5.8.4 and earlier contained an out-of-bounds read in ALPN handling when built with ALPN enabled HAVE ALPN / --enable-alpn. A crafted ALPN protocol list could trigger an out-of-bounds read, leading to a potential process cras...

A heap-buffer-overflow vulnerability exists in wolfSSL's wolfSSL d2i SSL SESSION function. When deserializing session data with SESSION CERTS enabled, certificate and session id lengths are read from an untrusted input without bounds validation, allowing an attacker to overflow fixed-size buffers...

PT-2026-26339

Heap Overflow in TLS 1.3 ECH parsing. An integer underflow existed in ECH extension parsing logic when calculating a buffer length, which resulted in writing beyond the bounds of an allocated buffer. Note that in wolfSSL, ECH is off by default, and the ECH standard is still evolving...

CVE-2022-38152

An issue was discovered in wolfSSL before 5.5.0. When a TLS 1.3 client connects to a wolfSSL server and SSLclear is called on its session, the server crashes with a segmentation fault. This occurs in the second session, which is created through TLS session resumption and reuses the initial struct...

CVE-2022-38153

An issue was discovered in wolfSSL before 5.5.0 when --enable-session-ticket is used; however, only version 5.3.0 is exploitable. Man-in-the-middle attackers or a malicious server can crash TLS 1.2 clients during a handshake. If an attacker injects a large ticket more than 256 bytes into a...

CVE-2022-42905

In wolfSSL before 5.5.2, if callback functions are enabled via the WOLFSSLCALLBACKS flag, then a malicious TLS 1.3 client or network attacker can trigger a buffer over-read on the heap of 5 bytes. WOLFSSLCALLBACKS is only intended for debugging...

CVE-2019-18840

In wolfSSL 4.1.0 through 4.2.0c, there are missing sanity checks of memory accesses in parsing ASN.1 certificate data while handshaking. Specifically, there is a one-byte heap-based buffer overflow inside the DecodedCert structure in GetName in wolfcrypt/src/asn.c because the domain name location...
