CVE-2025-36907

Local privilege escalation via surface image overflow

Published Sep 4, 2025 · Updated Sep 4, 2025

Heap buffer overflow in the Pixel Boot Loader in Google Android allows local users to gain elevated privileges through USB fastboot. The draw_surface_image() function in abl/android/lib/draw/draw.c writes beyond a heap buffer while rendering a supplied surface image. Exploitation requires an unlocked bootloader and user interaction; successful exploitation grants elevated local privileges.
