Descriptions
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: don't allow mapping the MMIO HDP page with large pages
We don't get the right offset in that case. The GPU has
an unused 4K area of the register BAR space into which you can
remap registers. We remap the HDP flush registers into this
space to allow userspace (CPU or GPU) to flush the HDP when it
updates VRAM. However, on systems with >4K pages, we end up
exposing PAGE_SIZE of MMIO space.
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/amdkfd: no permite mapear la página MMIO HDP con páginas grandes. En ese caso, no obtenemos el desplazamiento correcto. La GPU tiene un área 4K no utilizada del espacio BAR de registros en el que puede reasignar registros. Reasignamos los registros de descarga del HDP en este espacio para permitir que el espacio de usuario (CPU o GPU) vacíe el HDP cuando actualice la VRAM. Sin embargo, en sistemas con páginas >4K, terminamos exponiendo PAGE_SIZE del espacio MMIO.
