CVE-2025-70083

Local memory corruption via unchecked DirName copy

Published Feb 11, 2026 · Updated Feb 11, 2026

Stack-based buffer overflow in OpenSatKit 2.2.1 allows local users to overwrite adjacent stack memory via a crafted DirName telecommand. The File Manager directory handlers call strcpy on the ground-supplied DirName before FileUtil_AppendPathSep checks OS_MAX_PATH_LEN. The flaw requires low-privileged access to submit ground-segment telecommands; successful exploitation corrupts control data or crashes the affected process.
