Remote code execution via missing bounds check
Published Mar 24, 2023 · Updated Feb 28, 2025
Out-of-bounds write in Pixel cellular firmware in Android kernel allows remote attackers to execute code via cellular input. The firmware fails to validate an input boundary before writing, permitting data beyond the intended buffer to corrupt adjacent memory. Successful exploitation requires no privileges or user interaction and runs attacker-controlled code within the cellular firmware context.
