    CVE-2025-59438

        Observable Timing Discrepancy. The presence of a padding error could         leak through timings, enabling the attacker to recover information         about the secret.

    CVE-2026-34871

        On systems where getrandom() was not available, /dev/urandom would be         used a fallback instead of /dev/random.
