CVE-2024-44911Public exploitNetwork attack vector

Service crash via unchecked telecommand SPI

Published Sep 27, 2024 · Updated Mar 18, 2025

Out-of-bounds read in NASA CryptoLib 1.3.0 allows remote attackers to crash dependent systems via a crafted telecommand frame. Crypto_TC_ProcessSecurity passes the frame's SPI to get_sa_from_spi without checking the security-association array bounds, then dereferences the resulting invalid pointer. The frame must carry a valid GVCID but can use an out-of-range SPI, causing a segmentation fault in spacecraft or ground-station software that processes the frame.
