CVE-2025-37851

System crash via invalid OMAP plane value

Published May 9, 2025 · Updated May 11, 2026

Buffer overflow in Linux OMAP framebuffer code allows local users to crash the kernel through an invalid overlay-plane value. dispc_ovl_setup fails to reject OMAP_DSS_WB before downstream processing, causing dispc_ovl_setup_global_alpha to exceed its plane-indexed buffer. The published call path cannot initialize that value, so no presently reachable trigger is documented.
