EUVD-2026-39553

ML-KEM-1024 x64 AVX2 implicit rejection failure in the Fujisaki-Okamoto transform breaks IND-CCA2 security, allowing decapsulation to deviate from the implicit-rejection behavior required by the standard. The AVX2 constant-time ciphertext comparison used during decapsulation never compared the...

CVE-2026-10097

wolfSSL's AVX2-optimized ML-KEM implementation mlkemcmpavx2 compares only 1536 of the 1568 ciphertext bytes during the Fujisaki-Okamoto re-encryption check in ML-KEM-1024 decapsulation. Ciphertexts that differ from the expected re-encryption solely in bytes 1536-1567 bypass implicit rejection and...

GHSA-FHVH-VW7H-9XF3 libcrux-ml-dsa: Signature Verification on AVX2 Platforms Mishandles Edge Case

The AVX2 implementation of ML-DSA verification incorrectly implemented the usehint function, mishandling an edge case that should lead to signature rejection. Impact An attacker could make the ML-DSA verifier accept a crafted invalid signature under a maliciously generated verification key, if th...

A vulnerability in Legion of the Bouncy Castle Inc. BC-FJA BC-FIPS on Linux, X8664, AVX, AVX-512f. This vulnerability is associated with program files gcm128w, gcm512w. This issue affects BC-FJA: from 2.1.0 through 2.1.2...

Bouncy Castle LTS native GCM chunking can cause bad-tag exception on decryption

In Bouncy Castle LTS for Java, the AES/GCM native implementation used on Intel CPUs with AES PAA instruction sets AVX / VAES / VAESF variants can intermittently produce an incorrect authentication tag verification result during decryption when the ciphertext is fed in via a mix of update calls...

CVE-2026-43114

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftsetpipapoavx2: don't return non-matching entry on expiry New test case fails unexpectedly when avx2 matching functions are used. The test first loads a ranomly generated pipapo set with 'ipv4 . port' key, i.e. nft -...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the AES-CFB-128 process on x86-64 systems with AVX-512 and VAES support when processing partial cipher blocks. An attacker can cause a crash and application termination by providing input buffers that end at a memo...

GHSA-VC8C-J3XM-XJ73 Wasmtime segfault or unused out-of-sandbox load with f64.copysign operator on x86-64

On x86-64 platforms with AVX Wasmtime's compilation of the f64.copysign WebAssembly instruction with Cranelift may load 8 more bytes than is necessary. When signals-based-traps are disabled this can result in a uncaught segfault due to loading from unmapped guard pages. With guard pages disabled...

WasmTime buffer error vulnerability

Wasmtime is a lightweight WebAssembly runtime open source by the Bytecode Alliance. Versions of Wastime prior to 29.0.0, 36.0.5, 40.0.3, and 41.0.1 contained a buffer error vulnerability. This vulnerability arises due to Cranelift’s compilation of f64.copysign WebAssembly instructions on x86-64...

Siemens SIMATIC S7-1500 (CVE-2023-4807)

Issue summary: The POLY1305 MAC message authentication code implementation contains a bug that might corrupt the internal state of applications on the Windows 64 platform when running on newer X8664 processors supporting the AVX512-IFMA instructions. Impact summary: If in an application that uses...
