CWE-339
Small Seed Space in PRNG
A Pseudo-Random Number Generator (PRNG) uses a relatively small seed space, which makes it more susceptible to brute force attacks.
CVE-2024-10026 (GCVE-0-2024-10026)
Vulnerability from cvelistv5 – Published: 2025-01-30 19:12 – Updated: 2025-02-24 11:50
VLAI?
Summary
A weak hashing algorithm and small sizes of seeds/secrets in Google's gVisor allowed for a remote attacker to calculate a local IP address and a per-boot identifier that could aid in tracking of a device in certain circumstances.

Mitigation
Phase: Architecture and Design
Description:
- Use well vetted pseudo-random number generating algorithms with adequate length seeds. Pseudo-random number generators can produce predictable numbers if the generator is known and the seed can be guessed. A 256-bit seed is a good starting point for producing a "random enough" number.
Mitigation ID: MIT-2
Phases: Architecture and Design, Requirements
Strategy: Libraries or Frameworks
Description:
- Use products or modules that conform to FIPS 140-2 [REF-267] to avoid obvious entropy problems, or use the more recent FIPS 140-3 [REF-1192] if possible.
