"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmtd: Fix gluebi NULL pointer dereference caused by ftl notifier\n\nIf both ftl.ko and gluebi.ko are loaded, the notifier of ftl\ntriggers NULL pointer dereference when trying to access\n\u2018gluebi->desc\u2019 in gluebi_read().\n\nubi_gluebi_init\n ubi_register_volume_notifier\n ubi_enumerate_volumes\n ubi_notify_all\n gluebi_notify nb->notifier_call()\n gluebi_create\n mtd_device_register\n mtd_device_parse_register\n add_mtd_device\n blktrans_notify_add not->add()\n ftl_add_mtd tr->add_mtd()\n scan_header\n mtd_read\n mtd_read_oob\n mtd_read_oob_std\n gluebi_read mtd->read()\n gluebi->desc - NULL\n\nDetailed reproduction information available at the Link [1],\n\nIn the normal case, obtain gluebi->desc in the gluebi_get_device(),\nand access gluebi->desc in the gluebi_read(). However,\ngluebi_get_device() is not executed in advance in the\nftl_add_mtd() process, which leads to NULL pointer dereference.\n\nThe solution for the gluebi module is to run jffs2 on the UBI\nvolume without considering working with ftl or mtdblock [2].\nTherefore, this problem can be avoided by preventing gluebi from\ncreating the mtdblock device after creating mtd partition of the\ntype MTD_UBIVOLUME."
