CVE-2026-99007: drm/fb-helper: defer setup when fbdev_probe() fails, not just on -EAGAIN

Q: Which systems can reach the affected state?

Systems using the DRM fb-helper path can reach it when fbdev framebuffer probing fails after connected outputs and modes have already been recorded. The described failure includes a driver fbdev_probe() failure and is not limited to -EAGAIN.

Q: What event exposes the invalid configuration after the probe failure?

A later framebuffer-mode restore can commit the stale mode set even though its framebuffer is NULL. The reported path was drm_lastclose() during process exit, which reaches an atomic modeset commit and triggers WARN_ON(!set->fb).

Frequently Asked Questions

Which systems can reach the affected state?

Systems using the DRM fb-helper path can reach it when fbdev framebuffer probing fails after connected outputs and modes have already been recorded. The described failure includes a driver fbdev_probe() failure and is not limited to -EAGAIN.

What event exposes the invalid configuration after the probe failure?

A later framebuffer-mode restore can commit the stale mode set even though its framebuffer is NULL. The reported path was drm_lastclose() during process exit, which reaches an atomic modeset commit and triggers WARN_ON(!set->fb).

How can I identify a likely occurrence?

Look for an earlier fbdev probe failure followed by a DRM warning for a NULL framebuffer, specifically WARN_ON(!set->fb), during a restore or atomic modeset commit. The affected state has mode and connector data populated while mode_set->fb is NULL.
