CVE-2024-45550

Memory corruption via unchecked MCDM IOCTL index

Published Jan 6, 2025 · Updated Jan 6, 2025

Improper array-index validation in Qualcomm Snapdragon Compute's MCDM driver allows local users to corrupt memory through IOCTL calls. The driver processes an application's MCDM IOCTL set without validating an array index before using it, causing memory corruption. Low-privileged access is required; successful exploitation enables high-privileged code execution and information disclosure.
