CVE-2022-24402: Midnightblue Tetra:burst

High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days.

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.
