CVE-2020-11252

Information disclosure via disabled xPUs

Published Apr 7, 2021 · Updated Aug 4, 2024

Improper access control in Qualcomm Snapdragon platforms allows local users to disclose protected memory through TrustZone initialization when dumps are enabled. The initialization code disables xPU protections whenever memory-dump support is enabled, allowing accesses that should remain blocked and exposing memory contents. Exploitation requires high local privileges and user interaction to enable or trigger the dump path; the documented consequence is information disclosure.
