Local information disclosure via predictable heap allocation
Published Oct 30, 2023 · Updated Sep 17, 2024
Information disclosure in Scudo in Google Android 14 allows local users to infer heap allocation patterns without user interaction. The allocator uses an insecure implementation or design that makes allocation patterns predictable, but Google has not disclosed the faulty operation or attacker-controlled input. Local code execution is required, no additional execution privileges are needed, and the disclosed consequence is limited to information exposure.

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.
