CVE-2026-124000

NASA JPL ION-DTN 2.1.0 through 4.2.0 contains a heap buffer under-allocation vulnerability in the Asynchronous Message Service daemon (amsd) that allows a rogue or misconfigured peer to trigger an out-of-bounds write by sending crafted Meta-AMS (MAMS) configuration management messages that are processed without cryptographic authentication. Attackers can exploit the insufficient buffer size calculation for the internal state-event object to crash the active Configuration Server thread, causing a denial of service and potentially destabilizing subsequent shared-memory allocations in amsd.
