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