For example, a developer might forget to free up memory after the program no longer needs it, leading to a memory leak that quickly consumes all the availableRAM. Or the developer might free up an object's memory space without modifying a corresponding pointer, resulting in adangling pointerth...
The SockPuppet vulnerability was a use-after-free in the XNU kernel's in6_pcbdetach() function that was reachable through a series of socket-related syscalls. This function failed to clear the inp->in6p_outputopts field after freeing it and left the socket with a dangling pointer to a ip...
