CVE-2026-66391

CVE-2026-66391 affects Apache Wicket versions 9.0.0–9.23.0 and 10.0.0–10.9.0, due to a flaw described as Use of Insufficiently Random Values / Protection Mechanism Failure. The issue’s impact is mitigated by upgrading to version 10.10.0, which contains the fix. Connected documents reiterate the a...

CVE-2026-64456

CVE-2026-64456 affects the Linux kernel virtio-rng driver. A malicious or buggy virtio-rng backend can over-report used.len to trap memcpy past the inline data buffer, reading adjacent slab memory. This enables a potential cross-boundary data leak of guest-kernel heap contents via /dev/hwrng and ...

GHSA-VH45-F885-3848 sm-crypto: Predictable SM2 key generation in Node.js: default RNG uses Math.random + wall clock

Summary sm-crypto npm package 0.4.0, the latest release, published 2026-01-20 generates SM2 private keys and signing ephemeral scalars from a single module-wide RNG instance src/sm2/utils.js: const rng = new SecureRandom. SecureRandom is jsbn's PRNG, which seeds an ARC4 stream from...

USN-8595-2: Linux kernel (AWS) vulnerabilities

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 It was discovered that some AMD Zen 2 processors did not properly isolate shared...

CVE-2026-6924

A bug in the entropy initialization for SiWx917 causes the DRBG to use a predictable seed. As such, all random numbers generated in the Matter code use the same stream of numbers. This vulnerability was discovered after the impacted repository was already deprecated...

CVE-2026-16615 Librest: weak random number generation in pkce implementation

A flaw was found in librest. The PKCE implementation for OAuth authorization uses the GRand function from the GLib API, a cryptographically insecure pseudo-random number generator. Because the generated "code verifier" lacks sufficient cryptographic entropy, a malicious actor can reverse-engineer...

CVE-2026-8169

ExtremeXOS EXOS uses a challenge-response mechanism to authorize access to the privileged debug-mode function. The challenge value is generated using an insufficiently random source, which under certain conditions may allow an attacker to predict the expected response and activate debug-mode...

CVE-2026-8169

CVE-2026-8169 concerns ExtremeXOS (EXOS) where the privileged debug-mode access relies on a challenge-response mechanism. The challenge is generated from an insufficiently random source, allowing, under certain conditions, an attacker to predict the expected response and activate debug-mode witho...

CVE-2026-13577

The CVE-2026-13577 entry affects Dancer2 for Perl up to version 2.1.0. When secure PRNG sources (Math::Random::ISAAC::XS, Crypt::URandom) are unavailable, Dancer2::Core::Role::SessionFactory::generate_id falls back to a low-entropy, rand-derived session id. The fallback is computed from a SHA-1 h...

EUVD-2026-45896

Dancer2 versions through 2.1.0 for Perl generate insecure session ids when CSPRNG modules are unavailable. Dancer2::Core::Role::SessionFactory::generateid silently falls back to a built-in rand-derived session id when both Math::Random::ISAAC::XS and Crypt::URandom are unavailable. The fallback...
