  "details": "In the Linux kernel, the following vulnerability has been resolved:  dax/fsdev: use __va(phys) for kaddr in direct_access  Use __va(phys) instead of virt_addr + linear_offset for the kaddr return in __fsdev_dax_direct_access(). The previous code added a device-linear byte offset to virt_addr (which is __va of ranges[0]), but for multi-range devices with physical gaps between ranges, this linear arithmetic crosses the gap and produces a wrong kernel virtual address. Using __va(phys) where phys comes from dax_pgoff_to_phys() is correct for any range layout because the direct map translates each physical address independently.  This leaves dev_dax-\u003evirt_addr write-only, so remove the field (suggested by Dave Jiang).",
