CVE-2019-9471

Local privilege escalation via unchecked iATU region

Published Jan 6, 2020 · Updated Aug 4, 2024

Out-of-bounds write in the Android kernel for Pixel Neural Core allows local users with System privileges to elevate privileges. The set_outbound_iatu function multiplies an unchecked region value to derive an iATU register offset, then writes through the resulting out-of-range address. Exploitation requires existing System execution privileges on an affected Pixel device and no user interaction; the resulting memory corruption enables local privilege escalation.
