Linux Distros Unpatched Vulnerability : CVE-2026-3548

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Two buffer overflow vulnerabilities existed in the wolfSSL CRL parser when parsing CRL numbers: a heap- based buffer overflow could occur when improperly storin...

wolfSSL（CyaSSL） 安全漏洞

wolfSSL CyaSSL is a small, portable embedded SSL programming library developed by the American company wolfSSL, designed for developers working with embedded systems. Versions of wolfSSL CyaSSL prior to version 5.8.4 contained security vulnerabilities. These vulnerabilities stemmed from logical...

CVE-2026-3503: Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG)

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...

CVE-2026-3229: Heap-based Buffer Overflow

An integer overflow vulnerability existed in the static function wolfssladdtochain, that caused heap corruption when certificate data was written out of bounds of an insufficiently sized certificate buffer. wolfssladdtochain is called by these API: wolfSSLCTXaddextrachaincert,...

CVE-2026-3549: Heap-based Buffer Overflow

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-2026-2645: Improperly Implemented Security Check for Standard

In wolfSSL 5.8.2 and earlier, a logic flaw existed in the TLS 1.2 server state machine implementation. The server could incorrectly accept the CertificateVerify message before the ClientKeyExchange message had been received. This issue affects wolfSSL before 5.8.4 wolfSSL 5.8.2 and earlier is...

CVE-2026-2646: Heap-based Buffer Overflow

A heap-buffer-overflow vulnerability exists in wolfSSL's wolfSSLd2iSSLSESSION function. When deserializing session data with SESSIONCERTS enabled, certificate and session id lengths are read from an untrusted input without bounds validation, allowing an attacker to overflow fixed-size buffers and...

CVE-2026-4395: Heap-based Buffer Overflow

Heap-based buffer overflow in the KCAPI ECC code path of wceccimportx963ex in wolfSSL wolfcrypt allows a remote attacker to write attacker-controlled data past the bounds of the pubkeyraw buffer via a crafted oversized EC public key point. The WOLFSSLKCAPIECC code path copies the input to...

CVE-2026-3849: Out-of-bounds Write

Stack Buffer Overflow in wcHpkeLabeledExtract 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...
