CVE-2023-33021

Local memory corruption via graphics use-after-free

Published Sep 5, 2023 · Updated Aug 2, 2024

Use-after-free in Qualcomm Snapdragon Graphics allows local users to corrupt memory through crafted command-submission packets. Qualcomm identifies user-packet processing for graphics command submission as the locus but does not publish the responsible function or lifetime sequence. Local access is required, but prior privileges and user interaction are not; Qualcomm does not specify whether exploitation causes a crash or code execution.
