CVE-2023-21662

TEE memory corruption via unbounded response logging

Published Sep 5, 2023 · Updated Feb 27, 2025

Classic buffer overflow in Qualcomm Snapdragon Core Platform chipsets allows local users to corrupt TEE memory through response logging. The Core Platform logging path prints a response buffer without first bounding the copy to the destination capacity. Local low-privilege access is required; successful exploitation can disclose or modify protected data or interrupt execution within the affected TEE.
