CVE-2026-66372: Predictable Seed in Pseudo-Random Number Generator (PRNG)

The affected products use insufficiently random values, which allows web session tokens to be predictable, bounding token entropy to the seed space...

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...

EUVD-2026-40879

UltraVNC through 1.8.2.2 uses a cryptographically weak pseudo-random number generator to produce VNC authentication challenge bytes. In rfb/vncauth.c:119-129, the vncRandomBytes function seeds libc rand with time0 + getpid + rand and generates a 16-byte challenge. The combined seed space is...

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...

CVE-2026-34871

A predictable seed in a Pseudo-Random Number Generator (PRNG) affects Mbed TLS (before 3.6.6 and 4.x before 4.1.0) and TF-PSA-Crypto (before 1.1.0). Specifically, on systems where getrandom() is unavailable, /dev/urandom is used as a fallback instead of /dev/random . The impact of this vulnerabil...
