high

Description

In the Linux kernel, the following vulnerability has been resolved: mtd: virt_concat: fix use-after-free in mtd_virt_concat_destroy_joins() mtd_concat_destroy() frees item->concat so calling mtd_virt_concat_put_mtd_devices(item->concat) leads to a use after free. Fix this by moving mtd_virt_concat_put_mtd_devices() before mtd_concat_destroy()
