Remote code execution via unchecked mask size overflow
Published Jan 2, 2025 · Updated Mar 19, 2025
Heap overflow in Android 12, 12L, 13, 14, and 15 allows remote attackers to execute code via unspecified vectors without user interaction. prepare_to_draw_into_mask computes an image size from rounded mask bounds but allocates without rejecting a zero size that signals arithmetic overflow. The CNA reports that no privileges or user interaction are required; successful exploitation gives code execution in the affected process.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
