  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmtd: core: call _get_device() with the master MTD\n\n__get_mtd_device() calls the master's _get_device() callback with mtd,\nwhich may be a partition. __put_mtd_device() passes the master.\n\nThis breaks gluebi partitions because gluebi_get_device() uses\ncontainer_of() and therefore requires the master MTD. Pass the master\nto _get_device(), matching _put_device().",
