CVE-2026-39421

CVE-2026-39421 affects MaxKB (versions 2.7.1 and earlier). The sandbox escape occurs in ToolExecutor via Python ctypes calling raw syscalls to bypass LD_PRELOAD sandbox.so, enabling arbitrary code execution through direct kernel syscalls and potential full container/network compromise. The librar...
