CVE-2025-0478

Local physical-memory read and write via PMR export

Published Mar 24, 2025 · Updated Mar 24, 2025

Improper privilege handling in Graphics DDK 1.15 RTM through 24.3 RTM2 allows local users to read and write arbitrary physical memory. The PMMETA_PROTECT PMR is incorrectly exportable as a dma-buf file or GEM object, allowing improper GPU system calls to reach arbitrary physical pages. Software running as a non-privileged local user is sufficient; corruption can alter kernel or driver data and behavior.
