CVE-2025-30216 describes a critical heap overflow vulnerability in CryptoLib versions 1.3.3 and prior, affecting the software-only implementation of the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) used in spacecraft communications. An attacker can trigger this vulnerability by crafting a malicious TM protocol packet with an oversized Secondary Header Length, leading to a memcpy operation that overwrites adjacent heap memory. This allows for potential arbitrary code execution or system instability with a CVSS score of 9.1 (CRITICAL), indicating a network-exploitable vulnerability with low attack complexity and high impact on integrity and availability. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
