CVE-2022-33214

Local memory corruption via metadata-size race

Published Oct 17, 2022 · Updated May 14, 2025

Memory corruption in Qualcomm Snapdragon display components allows local users to corrupt memory through a metadata-size race. The display component checks the metadata reserved size and later uses it without ensuring that the value remains unchanged, creating a time-of-check time-of-use window. Local access without prior privileges or user interaction is sufficient, while Qualcomm has not published a more specific post-corruption outcome.
