Physical privilege escalation via baseband buffer overwrite
Published Mar 10, 2026 · Updated Mar 10, 2026
Out-of-bounds write in the Shannon baseband of Google Android allows physically proximate attackers to escalate privileges without authentication. The usim_SendMCCMNCIndMsg function in usim_Registration.c writes beyond its intended buffer and corrupts memory. Physical access is required, but neither prior execution privileges nor user interaction is needed; successful exploitation grants elevated privileges on affected devices.

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.
