WebAddressSanitizer tags every 8 bytes of the application memory with a 1 byte tag (using shadow memory ), uses redzones to find buffer-overflows and quarantine to find use-after-free. The redzones, the quarantine, and, to a less extent, the shadow, are the sources of AddressSanitizer’s memory overhead. See the AddressSanitizer paper for details.
