【中文导读】该 CVE 涉及安全缺陷（高危风险）。具体受影响产品、版本和修复方案以 NVD/厂商公告为准。 【原始描述】The TETRA TEA1 keystream generator implements a key register initialization function that compresses the 80-bit key to only 32 bits for usage during the keystream generation phase, which is insufficient to safeguard against exhaustive search attacks.
