CVE-2026-16280

An integer overflow when calculating physical offsets for sparse PMRs may result in 32-bit truncation of address computations for PMRs larger than 4 GB. This can lead to incorrect GPU MMU mappings and may allow a non-privileged user to trigger access to unintended physical memory, resulting in memory corruption or information disclosure.

Summary		(es) Un desbordamiento de entero al calcular los desplazamientos físicos para PMR dispersos puede resultar en un truncamiento de 32 bits de los cálculos de direcciones para PMR mayores de 4 GB. Esto puede llevar a asignaciones incorrectas de la MMU de la GPU y puede permitir a un usuario no privilegiado desencadenar el acceso a memoria física no prevista, lo que resulta en corrupción de memoria o revelación de información.
