Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: x86/coco: Requires seeding the RNG with RDRAND on CoCo systems. There are few uses of CoCo that do not rely on functional cryptography and, consequently, a functioning RNG. Unfortunately, the CoCo threat model means that the VM...

Astra Linux – Vulnerability in mbedtls

A issue was discovered in Mbed TLS before 3.6.6 and 4.x before 4.1.0, as well as in TF-PSA-Crypto before 1.1.0. There is a predictable seed in a pseudo-random number generator PRNG...

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-2026-13199

CVE-2026-13199 affects Raspberry Pi 5 and Compute Module 5 EEPROM firmware. The issue is that the EEPROM produced non-random KASLR and RNG seed values, resulting in consistent kernel addresses across boots and devices. This may lower entropy and potentially ease exploitation of other vulnerabilit...

PT-2026-56167

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...

USN-8475-1: AMD Microcode vulnerabilities

Oleksii Oleksenko, Cedric Fournet, Jana Hofmann, Boris Köpf, Stavros Volos, and Flavien Solt discovered that some AMD processors may allow an attacker to infer data from previous stores, potentially resulting in the leakage of privileged information. A local attacker could possibly use this to...

CVE-2026-9692

Mojolicious::Sessions::Storable versions through 0.05 for Perl generate session ids insecurely. The default session id generator returns a SHA-1 hash seeded with the built-in rand function, the epoch time, the heap address of an anonymous hash, and the PID. These are predictable or low-entropy...

CVE-2026-9692 Mojolicious::Sessions::Storable versions through 0.05 for Perl generate session ids insecurely

Mojolicious::Sessions::Storable versions through 0.05 for Perl generate session ids insecurely. The default session id generator returns a SHA-1 hash seeded with the built-in rand function, the epoch time, the heap address of an anonymous hash, and the PID. These are predictable or low-entropy...

CVE-2026-40514

SmarterTools SmarterMail builds prior to 9610 contain a cryptographic weakness in the file and email sharing endpoints that use DES-CBC encryption with keys and initialization vectors derived from System.Random seeded with insufficient entropy, reducing the seed space to approximately 19,000...

kernel: fs: writeback: fix use-after-free in __mark_inode_dirty()

In the Linux kernel, the following vulnerability has been resolved: fs: writeback: fix use-after-free in markinodedirty An use-after-free issue occurred when markinodedirty get the bdiwriteback that was in the progress of switching. CPU: 1 PID: 562 Comm: systemd-random- Not tainted...

CVE-2026-5084

WebDyne::Session versions before 3.003704 for Perl generate the session id insecurely. The session handler generates the session id from an MD5 hash seeded with a call to the built-in rand function. The rand function is passed a maximum value based on the process id, the epoch time and the...

JLSEC-2026-465 Mbed TLS may use a low entropy PRNG seed

An issue was discovered in Mbed TLS before 3.6.6 and 4.x before 4.1.0 and TF-PSA-Crypto before 1.1.0. There is a Predictable Seed in a Pseudo-Random Number Generator PRNG...

ruby: Properly initialize the random number generator when forking new process

Ruby before 1.8.6-p114 does not reset the random seed upon forking, which makes it easier for context-dependent attackers to predict the values of random numbers by leveraging knowledge of the number sequence obtained in a different child process, a related issue to CVE-2003-0900...

EUVD-2026-20063

Ado::Sessions versions through 0.935 for Perl generates insecure session ids. The session id is generated from a SHA-1 hash seeded with the built-in rand function, the epoch time, and the PID. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked fr...

CVE-2026-5082

The Amon2::Plugin::Web::CSRFDefender Perl module, versions 7.00 through 7.03 , contains a vulnerability where the generate_session_id function produces insecure session IDs . The root cause is that if the /dev/urandom device is unavailable, the system falls back to generating bytes using a SHA-1 ...
