Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: hwrng: cavium – fixed the NULL but dereferenced coccicheck error. Fixed the following coccicheck warnings: ./drivers/char/hwrandom/cavium-rng-vf.c:182:17-20: ERROR: pdev is NULL but was dereferenced...

PT-2026-89092

In the Linux kernel, the following vulnerability has been resolved: crypto: qcom-rng - Allow zero as a random number Zero is a valid random number and needs to be allowed. Otherwise the output is distinguishable from random...

EUVD-2026-71501

In the Linux kernel, the following vulnerability has been resolved: crypto: xilinx-trng - Remove cryptorng interface Implementing the cryptorng interface has no purpose, as it isn't used in practice. It's being removed from other drivers too. Just remove it. This leaves hwrng, which is actually...

CVE-2026-80835

In the Linux kernel, the following vulnerability has been resolved: crypto: qcom-rng - Remove cryptorng interface qcom-rng.c exposes the same hardware through two completely separate interfaces, cryptorng and hwrng. However, the implementation of this is buggy because it permits generation...

The vulnerability in the `src/havegecmd.c` component of the Haveged random number generator allows a hacker to cause a service failure.

The vulnerability of the src/havegecmd.c component, which generates random numbers for Haveged, is related to the bypassing of authentication due to a fundamental error. Exploiting this vulnerability could allow an attacker to cause service failures...

Astra Linux – Vulnerability in pgagent

When batch jobs are executed by pgAgent, a script is created in a temporary directory and then executed. In versions of pgAgent prior to 4.2.3, an insufficiently seeded random number generator was used when generating the directory name, which allows a local attacker to pre-create the directory a...

nanoid: nanoid: Predictable ID generation due to integer overflow

A flaw was found in nanoid, a JavaScript library for generating unique string IDs. A remote attacker could exploit an integer overflow vulnerability by providing a specific input to the nanoidsize function. This issue causes the internal random number generator to become predictable, leading to t...

CVE-2026-8470

IBM Langflow OSS 1.0.0 through 1.10.3, 1.0.0 through 1.10.3, 1.0.0 through 1.10.3, and 1.0.0 through 1.10.3 use Python's non-cryptographic random module for generating Fernet encryption keys from user secrets under 32 characters. The deterministic Mersenne Twister PRNG produces identical keys for...

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

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...
