CVE-2019-10574

Memory disclosure via unchecked HLOS data offsets

Published Apr 16, 2020 · Updated Aug 4, 2024

Out-of-bounds read in Qualcomm Snapdragon firmware allows local users to read protected memory or crash a trustlet via HLOS data offsets. The kmota trusted application's command path uses offsets supplied by the high-level operating system without checking that they remain within the input buffer. Access requires a local low-privileged process able to submit requests to the secure environment; malformed offsets expose memory or interrupt the trustlet without modifying data.
