Local information disclosure via namespace buffer validation
Published Sep 15, 2026 · Updated Sep 15, 2026
Information disclosure in validate_ns_buf in Google Android's mbu_class.rs allows local users with System privileges to obtain information. The function inadequately validates a namespace buffer, but public records do not identify the unchecked condition or the disclosed data. Exploitation requires local System-level execution and no user interaction; the documented consequence is limited to information disclosure.
