The function morse_page_slicing_process_tim_element() in page_slicing.c derives the TIM bitmap length directly from a received IE field without validating it against the fixed-size destination buffer before passing it to memset and memcpy operations, allowing up to 252 bytes of attacker-controlled data to be written beyond the buffer boundary. Because beacons are broadcast frames processed during passive scanning, no authentication, association, or user interaction is required."
