MEDIUM 6.7
Description
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).
Analysis
Mbed TLS 3.x before 3.6.6, 4.x before 4.1.0, and TF-PSA-Crypto before 1.1.0 contain a predictable seed vulnerability in their pseudo-random number generator (PRNG) implementation that compromises the cryptographic strength of generated random values. Attackers with knowledge of the seed initialization mechanism can predict PRNG output, enabling them to forge cryptographic material, decrypt communications, or impersonate legitimate parties. …
