CVE-2024-43091Network attack vector

Remote code execution via overflowed mask allocation

Published Nov 13, 2024 · Updated Dec 4, 2024

Integer overflow in Android 12 through 15 allows remote attackers to execute code through Skia emboss-mask processing without user interaction. SkEmbossMaskFilter::filterMask calculates a three-dimensional mask allocation without rejecting integer overflow, allowing later writes beyond the allocated buffer. No privileges or user interaction are required; successful exploitation grants code execution in the affected System component.
