Local information disclosure via undersized RSA key
Published Jun 16, 2026 · Updated Jun 16, 2026
Out-of-bounds read in Android's bootloader AVB RSA parser allows local users to disclose memory through a malformed public-key buffer. iavb_parse_key_data calls avb_rsa_public_key_header_validate_and_byteswap before ensuring the input contains a complete AvbRSAPublicKeyHeader. A local user with low privileges can trigger the read without user interaction, exposing adjacent memory but not enabling modification or service interruption.

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.
