CVE-2024-29784

Local privilege escalation via overflowed response sizing

Published Jun 13, 2024 · Updated Aug 2, 2024

An integer overflow in the lwis kernel component of Google Pixel devices allows local users to escalate privileges without interaction. The prepare_response function in lwis_periodic_io.c performs overflow-prone size arithmetic, causing an out-of-bounds write. Local code execution on an affected device is required, but no additional execution privileges or user interaction is needed to gain elevated access.
