CVE-2020-11161

Memory disclosure and service interruption via negative-width alignment

Published Jun 9, 2021 · Updated Aug 4, 2024

Buffer over-read in Qualcomm Snapdragon graphics components allows local users to read adjacent memory and interrupt service. The alignment calculation accepts a negative width from an external component and accesses memory out of bounds while deriving alignment requirements. Reachability requires local access to an affected device and a path that supplies the crafted width to the closed-source graphics component.
