Recommendations: For CloudEngine 5800, update to a version that fixes the pointer double free vulnerability. For CloudEngine 6800, update to a version that fixes the pointer double free vulnerability. For CloudEngine 7800, update to a version that fixes the pointer double free vulnerability. For CloudEngine 12800, update to a version that fixes the pointer double free vulnerability. As a temporary workaround, consider restricting access to the functional modules that use the copied memory pointer to minimize the risk of exploitation.
