Remote code execution via font-layer integer overflow
Published Sep 8, 2026 · Updated Sep 10, 2026
Integer overflow in the System component of Google Android 14 through 17 allows remote attackers to execute arbitrary code. The tt_face_colr_blend_layer function in ttcolr.c performs integer arithmetic that overflows while blending COLR font-layer data. No user interaction or additional execution privileges are required, and successful exploitation can also escalate privileges on the affected device.
