Remote code execution via unchecked baseband input
Published Oct 11, 2023 · Updated Sep 18, 2024
Stack-based buffer overflow in Google Android's Shannon baseband allows remote attackers to execute code without user interaction. The baseband processes attacker-controlled data without the required bounds check and can overwrite a stack buffer, but Google has not disclosed the affected function or input format. Exploitation requires network reachability to a supported Pixel device's cellular baseband and grants code execution in that component without prior privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
