Summary

Hide ▲

Nearby attackers can crash AirDrop and bypass Quick Share session checks, exposing Apple, Samsung, and Google Windows file-sharing stacks to local disruption and possible exploitation. The flaws reach sharingd on macOS and iOS, and one issue sits in Google's Quick Share for Windows memory handling. Attackers need wireless proximity or the same local network, but they do not need prior pairing or user interaction. Apple has patched one bug and Google has landed a Windows fix, while the rest remain under coordinated disclosure.
