DisplayPort binding failure via mis-scoped endpoint lifetime
Published Sep 17, 2025 · Updated Sep 17, 2025
Resource-management flaw in Linux kernel 5.19 through 6.0.6 allows local users to prevent DisplayPort device binding. In drivers/gpu/drm/msm/dp/dp_display.c, endpoint resources created after component bind remain tied to the DP controller platform device instead of the aggregate DRM device. A Qualcomm DisplayPort AUX bus and deferred aggregate binding are required; a retry leaks resources or fails because the endpoint is already populated.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
