CVE-2022-33281

Memory corruption via unchecked EVA kernel index

Published May 2, 2023 · Updated Aug 3, 2024

Memory corruption in Qualcomm Snapdragon computer vision allows local users with high privileges to corrupt EVA kernel memory. The EVA kernel test path accepts an array index without proper validation when invoked without sending any frames, enabling an out-of-bounds array access. Access requires a local, high-privilege context; Qualcomm reports confidentiality, integrity, and availability impact but discloses no further exploit mechanics.
