+Deallocating memory more than once can lead to a double-free vulnerability. This can be exploited to +corrupt the allocator's internal data structures, which can lead to denial-of-service attacks by crashing +the program, or security vulnerabilities, by allowing an attacker to overwrite arbitrary memory locations. +
+ ++Ensure that all execution paths deallocate the allocated memory at most once. If possible, reassign +the pointer to a null value after deallocating it. This will prevent double-free vulnerabilities since +most deallocation functions will perform a null-pointer check before attempting to deallocate the memory. +
