A 0-click exploit chain for the Pixel 10: When a Door Closes, a Window Opens
We recently published an exploit chain for the Google Pixel 9 that demonstrated it was possible to go from a zero-click context to root on Android in just two exploits. The Dolby 0-click vulnerability existed across all of Android, until it was patched in January 2026. While we had an exploit chain for the Pixel 9, we wanted to see if it was possible to write a similar exploit chain for Pixel 10. Updating the Dolby Exploit Altering our exploit for CVE-2025-54957 was fairly straightforward. The majority of needed changes involved updating offsets calculated for the specific version of the library we targeted on the Pixel 9 to similar offsets in the library for Pixel 10.
A 0-click exploit chain for the Pixel 9 Part 1: Decoding Dolby
Over the past few years, several AI-powered features have been added to mobile phones that allow users to better search and understand their messages. One effect of this change is increased 0-click attack surface, as efficient analysis often requires message media to be decoded before the message is opened by the user. One such feature is audio transcription. Incoming SMS and RCS audio attachments received by Google Messages are now automatically decoded with no user interaction. As a result, audio decoders are now in the 0-click attack surface of most Android phones. I’ve spent a fair bit of time investigating these decoders, first reporting CVE-2025-49415 in the Monkey’s Audio codec on Samsung devices. Based on this research, the team reviewed the Dolby Unified Decoder, and Ivan Fratric and I reported CVE-2025-54957 .
