CVE-2026-3503: CWE-335 Incorrect Usage of Seeds in Pseudo-Random Number Generator (PRNG) in wolfSSL Inc. wolfSSL (wolfCrypt)CVE-2026-3503 0 CVE-2026-3503 is a medium severity vulnerability in wolfSSL's wolfCrypt library version 5.8.2 affecting ARM Cortex-M microcontrollers. The flaw involves incorrect usage of seeds in the pseudo-random number generator (PRNG) within post-quantum cryptographic implementations (ML-KEM and ML-DSA). Physical attackers can induce transient faults to corrupt or redirect seed or pointer values during the Keccak-based expansion process, potentially compromising key material or cryptographic outcomes. Exploitation requires physical access and high attack complexity, with no user interaction needed. This vulnerability impacts confidentiality due to possible key leakage but has limited scope and availability impact. No known exploits are reported in the wild. Organizations using affected wolfSSL versions on ARM Cortex-M devices should prioritize patching or apply hardware-level protections against fault injection attacks.
