Description
Description
In the Linux kernel, the following vulnerability has been resolved:
dax/fsdev: clear vmemmap_shift when binding static pgmap
Clear pgmap->vmemmap_shift for static DAX devices. When rebinding a static
device from device_dax (which may set vmemmap_shift based on alignment) to
fsdev_dax, the stale vmemmap_shift persists on the shared pgmap. Explicitly
zero it before devm_memremap_pages() so the vmemmap is built for order-0
folios as fsdev requires.
