      "title": "dax/kmem: account for partial discontiguous resource upon removal",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndax/kmem: account for partial discontiguous resource upon removal\n\nWhen dev_dax_kmem_probe() partially succeeds (at least one range is\nmapped) but a subsequent range fails request_mem_region() or\nadd_memory_driver_managed(), the probe silently continues, ultimately\nreturning success, but with the corresponding range resource NULL'ed out.\n\ndev_dax_kmem_remove() iterates over all dax_device ranges regardless of if\nthe underlying resource exists.  When remove_memory() is called later, it\nreturns 0 because the memory was never added which causes\ndev_dax_kmem_remove() to incorrectly assume the (nonexistent) resource can\nbe removed and attempts cleanup on a NULL pointer.\n\nFix this by skipping these ranges altogether, noting that these cases are\nconsidered success, such that the cleanup is still reached when all\nactually-added ranges are successfully removed.",
