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...

CVE-2026-3579: Observable Discrepancy

wolfSSL 5.8.4 on RISC-V RV32I architectures lacks a constant-time software implementation for 64-bit multiplication. The compiler-inserted muldi3 subroutine executes in variable time based on operand values. This affects multiple SP math functions sp256mul9, sp256sqr9, etc., leading to a timing...

CVE-2026-4159: Out-of-bounds Read

1-byte OOB heap read in wcPKCS7DecodeEnvelopedData via zero-length encrypted content. A vulnerability existed in wolfSSL 5.8.4 and earlier, where a 1-byte out-of-bounds heap read in wcPKCS7DecodeEnvelopedData could be triggered by a crafted CMS EnvelopedData message with zero-length encrypted...

CVE-2026-3580: Observable Discrepancy

In wolfSSL 5.8.4, constant-time masking logic in sp256getentry2569 is optimized into conditional branches bnez by GCC when targeting RISC-V RV32I with -O3. This transformation breaks the side-channel resistance of ECC scalar multiplication, potentially allowing a local attacker to recover secret...

CVE-2026-1005: Integer Underflow (Wrap or Wraparound)

Integer underflow in wolfSSL packet sniffer = 5.8.4 allows an attacker to cause a buffer overflow in the AEAD decryption path by injecting a TLS record shorter than the explicit IV plus authentication tag into traffic inspected by sslDecodePacket. The underflow wraps a 16-bit length to a large...

Azure Linux 3.0 Security Update: CBL-Mariner Releases (CVE-2025-13912)

The version of CBL-Mariner Releases installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-13912 advisory. - Multiple constant-time implementations in wolfSSL before version 5.8.4 May be transformed into...

Azure Linux 3.0 Security Update: cmake (CVE-2024-2379)

The version of cmake installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-2379 advisory. - libcurl skips the certificate verification for a QUIC connection under certain conditions, when built to use...

CBL Mariner 2.0 Security Update: CBL-Mariner Releases (CVE-2025-13912)

The version of CBL-Mariner Releases installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-13912 advisory. - Multiple constant-time implementations in wolfSSL before version 5.8.4 May be transformed into...

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...
