CVE-2024-50096

Sensitive data disclosure via unchecked firmware copy

Published Nov 5, 2024 · Updated Aug 5, 2026

Information disclosure in the Linux nouveau/dmem component allows local users to receive sensitive data from a dirty HIGH_USER page. The nouveau_dmem_copy_one function sends a copy push command to firmware but does not verify successful execution, so migrate_to_ram can return an uncleared page after a copy error. Exploitation requires local low-privileged access and a Nouveau device-memory migration copy failure; exposure is limited to data present in the returned page.
