Local information disclosure via incorrect bounds check
Published Jun 15, 2022 · Updated Aug 3, 2024
Out-of-bounds read in Google Titan M allows local users with System privileges to disclose protected memory via P-256 ASN.1 input. The asn1_p256_int routine in crypto/asn1.c applies an incorrect bounds check and reads beyond the intended buffer while processing an integer. Exploitation requires existing System execution privileges and no user interaction; the public record does not identify the exposed data.
