Local information disclosure via Scudo heap OOB access
Published Oct 30, 2023 · Updated Sep 6, 2024
Information disclosure in Scudo in Google Android 14 allows local users to read heap data through out-of-bounds memory access. Scudo's allocator design permits certain heap operations to read or write beyond intended bounds; Google has not published the specific code locus. A local user needs no additional execution privileges or user interaction, and the reported consequence is limited to information disclosure.
