A 0-click exploit chain for the Pixel 9 Part 3: Where do we go from here?

Google Project Zero uncovered a 0-click exploit chain targeting the Pixel 9, leveraging vulnerabilities in the Dolby UDC audio decoder and the BigWave kernel driver. The chain allowed remote code execution and privilege escalation with minimal bugs, highlighting weaknesses in Android's attack surface, driver security, and patching timelines. Despite responsible disclosure, patch deployment was delayed, leaving users exposed for months. The findings emphasize systemic issues in vulnerability prioritization, mitigation effectiveness, and vendor coordination across the Android ecosystem.
