CVE-2026-45201

Software installed and run as a non-privileged user may conduct improper GPU system calls to pass invalid log2 page size when allocating physical pages leading to OOB read and/or write due to improper validation of the said value. Such crafted log2 page size could lead to 4K pages being treated as higher order pages and allowing read and/or write access to the memory beyond 4K threshold.

Summary		(es) El software instalado y ejecutado como un usuario no privilegiado puede realizar llamadas al sistema de GPU impropias para pasar un tamaño de página log2 inválido al asignar páginas físicas, lo que lleva a una lectura y/o escritura fuera de límites (OOB) debido a la validación incorrecta de dicho valor. Dicho tamaño de página log2 manipulado podría llevar a que las páginas de 4K sean tratadas como páginas de orden superior y permitir el acceso de lectura y/o escritura a la memoria más allá del umbral de 4K.
