CVE-2020-11261Known exploitation

Memory corruption via unchecked oversized allocation

Published Jun 9, 2021 · Updated Oct 21, 2025

Improper input validation in Qualcomm Snapdragon Graphics allows local users to corrupt memory through an oversized allocation request. The graphics memory-allocation path fails to return an error for an excessively large request, allowing subsequent processing to corrupt memory. A local user application can trigger the flaw without user interaction; public details do not identify the corrupted object or resulting primitive.
