CVE-2026-90215 | BDVDB-2026-375994 Detail

Description#

In the Linux kernel, the following vulnerability has been resolved: mtd: ubi: Release device reference on busy detach ubi_detach_mtd_dev() obtains a device reference through ubi_get_device() before checking whether the UBI device is busy. The busy return path drops ubi->ref_count but leaves the device reference held, so the device object cannot be released after a later detach. Drop the device reference before returning -EBUSY.
