In draw_surface_image() of abl/android/lib/draw/draw.c, there is a possible out of bounds write due to a heap buffer overflow. This could lead to local escalation of privilege via USB fastboot, after a bootloader unlock, with no additional execution privileges needed. User interaction is needed for exploitation.
