In the Linux kernel, the following vulnerability has been resolved: crypto: loongson - Remove broken and unused loongson-rng The loongson-rng rngalg has several vulnerabilities, including not providing forward security, and a use-after-free bug due to the use of waitforcompletioninterruptible...

CVE-2026-64306

CVE-2026-64306 affects the Linux kernel 's crypto subsystem, specifically the CTR_DRBG (Counter-mode Deterministic Random Bit Generator) implementation. The function drbg_ctr_generate() sometimes returns success when it actually fails, leaving the output buffer uninitialized. This can lead to den...

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-2026-13577 Dancer2 versions before 2.2.0 for Perl generate insecure session ids when required CSPRNG modules are unavailable

Dancer2 versions before 2.2.0 for Perl generate insecure session ids when required CSPRNG modules are unavailable. Dancer2::Core::Role::SessionFactory::generateid silently falls back to a built-in rand-derived session id unless both Math::Random::ISAAC::XS and Crypt::URandom are available. The...

CVE-2026-9323

The urwid web display backend urwid/display/web.py generates web session identifiers urwidid in Screen.start by concatenating two random.randrange109 calls that use Python's Mersenne Twister PRNG, which is not cryptographically secure. Each call consumes approximately 30 bits of PRNG state, and t...

CVE-2026-13082

GD::SecurityImage versions through 1.75 for Perl use rand to generate secrets. The random method creates the challenge text used for the CAPTCHA by sampling characters from an array using Perl's built-in rand function, and generates a by default six-character string. The built-in rand function is...

Security Evaluation of Laser-Phase-Noise Quantum Random Number Generators with Intrinsic Correlations

Quantum random number generators are essential for achieving information-theoretical security in modern cryptographic systems. Among various implementations, laser phase noise schemes are widely favored for their simple architecture and high integration potential. However, the intrinsic...

CVE-2026-61500

Rejetto HFS 3.0.0 through 3.2.0 derives its session-cookie signing key from the non-cryptographic Math.random generator and discloses outputs of the same generator to unauthenticated clients during login. A remote attacker can collect a small number of login responses, reconstruct the generator's...

PT-2026-59273

An issue was discovered in Matrix Sydent before 1.0.3 and Synapse before 0.99.3.1. Random number generation is mishandled, which makes it easier for attackers to predict a Sydent authentication token or a Synapse random ID...

CVE-2026-13199

EEPROM firmware on Raspberry Pi 5 and Compute Module 5 devices produced non-random KASLR and RNG seed values. This resulted in consistent kernel addresses across boots and devices, potentially making it easier to exploit other vulnerabilities. Additionally, the low-quality RNG seed may affect the...

CVE-2026-13199 Insufficient Entropy in Raspberry Pi 5 and Compute Module 5

EEPROM firmware on Raspberry Pi 5 and Compute Module 5 devices produced non-random KASLR and RNG seed values. This resulted in consistent kernel addresses across boots and devices, potentially making it easier to exploit other vulnerabilities. Additionally, the low-quality RNG seed may affect the...

CVE-2026-56016 CGI::Session::ID::md5 versions before 4.49 for Perl generate predictable session ids from low-entropy sources

CGI::Session::ID::md5 versions before 4.49 for Perl generate predictable session ids from low-entropy sources. The generateid method builds the session id from a MD5 digest of the process id, the epoch time, and the built-in rand function. All three are predictable, low-entropy sources: the PID i...
