CVE-2026-89599

Unspecified impact via premature display registration

Published Sep 11, 2026 · Updated Sep 11, 2026

Race condition in the Linux panel-dsi-cm driver allows attackers to cause unspecified impact via concurrent display callbacks. The dsicm_probe function publishes the display through omapdss_register_display before initializing ddata->lock, so a consumer callback can attempt to take an uninitialized mutex. Reachability requires the affected OMAP DSI command-mode panel driver and a callback during the narrow probe-time interval; the upstream record specifies neither a user-controlled trigger nor a bounded operational consequence.
