CVE-2025-68181

Kernel memory corruption via double device release

Published Dec 16, 2025 · Updated Dec 16, 2025

Use-after-free in the Linux kernel Radeon DRM driver allows local users to corrupt kernel memory during failed probe or device removal. After devm_drm_dev_alloc() transfers lifetime management to devres, the probe-error and removal paths still call drm_put_dev(), releasing the DRM device before devres releases it again. Access to an affected Radeon device and a teardown path are required; the stale device can expose or alter kernel memory and interrupt the GPU or kernel.
