CVE-2024-47029

Local information disclosure via incorrect shared-memory bounds check

Published Oct 25, 2024 · Updated Oct 25, 2024

Out-of-bounds read in Google Pixel Faceauth allows local users to disclose memory through a malformed shared-memory request. The TrustySharedMemoryManager::GetSharedMemory method in ondevice/trusty/trusty_shared_memory_manager.cc applies an incorrect bounds check before reading shared memory. Exploitation needs no user interaction, and the documented consequence is memory disclosure without integrity or availability impact.
