Basically, a new flaw lets hackers attack your Pixel 9 without you clicking anything.
A serious 0-click exploit has been found in the Pixel 9's Dolby decoder. This flaw could allow hackers to compromise your device without any interaction. It's crucial to update your phone and stay alert to protect your data.
What Happened
A new 0-click exploit has been discovered in the Dolby Unified Decoder? of the Google Pixel 9. This vulnerability allows attackers to execute malicious code without any user interaction, making it particularly dangerous. The exploit takes advantage of how audio files are automatically decoded by the phone, which has become a growing attack surface due to recent AI features in mobile devices.
Researchers from Project Zero identified two critical vulnerabilities: CVE-2025-54957 in the Dolby decoder and CVE-2025-36934 related to a driver on the Pixel 9. These vulnerabilities expose most Android devices to potential attacks, as they involve the automatic processing of audio attachments? in messages. The findings raise concerns about the security of modern Android systems and the effectiveness of their defenses against such exploits.
Why Should You Care
You might think your phone is safe, but this 0-click vulnerability means you could be attacked without even knowing it. Imagine receiving a seemingly harmless audio message, only to have your device compromised instantly. This could lead to unauthorized access to your personal data, like messages, photos, or even banking information.
