CVE-2026-0040Network attack vector

Remote device crash via UBSan hard abort

Published Jun 1, 2026 · Updated Jun 1, 2026

Integer overflow in Android 14, 15, 16, and 16-qpr2 allows remote authenticated users to crash devices through UBSan runtime handlers. The dng_sdk build previously linked UBSan's minimal runtime, whose arithmetic-overflow handlers abort execution; the patch replaces them with exceptions. A low-privileged remote context can trigger the failure without user interaction, interrupting availability without reported data exposure or modification.
