CVE-2022-33221

Local information disclosure via metadata buffer over-read

Published Feb 9, 2023 · Updated Aug 3, 2024

Buffer over-read in the Trust Management Engine in Qualcomm Snapdragon chipsets allows local users to disclose trusted-environment data. The proprietary metadata-verification request handler reads beyond its intended buffer, but Qualcomm has not disclosed the responsible field or missing bounds check. Local access is required, with no prior privileges or user interaction; the reported consequence is bounded to information exposure and limited availability impact.
