CVE-2025-62600Public exploitNetwork attack vector

Remote crash via oversized binary-property allocation

Published Feb 3, 2026 · Updated Feb 3, 2026

Integer overflow in Fast DDS allows remote attackers to crash DDS processes through a crafted SPDP DATA submessage. readBinaryPropertySeq multiplies an attacker-controlled 32-bit sequence count by 12, permits wraparound past its bounds check, and resizes binary_properties to that count. DDS Security must be enabled, but token parsing occurs before trust is established, so an on-network forged or replayed SPDP packet terminates the process.
