Executive brief
A critical vulnerability exists in the modem component of Google Pixel devices. This component handles cellular connectivity, and a flaw in how it processes data could allow a remote attacker to take control of the device without any user interaction. This could lead to a total compromise of the device, including unauthorized access to data or disruption of service.
Technical details
An out-of-bounds read vulnerability exists in the Modem component of Google Pixel devices due to a missing bounds check. The vulnerability is classified as Remote Code Execution (RCE) and can be exploited over the network without requiring any additional execution privileges or user interaction. This suggests a pre-authentication attack vector via cellular radio signaling. Google has addressed this issue in the June 2026 Pixel Security Bulletin.
