CVE-2026-90215 in Linuxthông tin

Tóm tắt

Bởi MITRE • 17/09/2026

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.
