CWEhttps://cwe.mitre.org/data/definitions/672.html

In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfs_btrfs_ioctl_fd_replace() installs an fd referencing a file from the lower filesystem without taking an additional reference to that file. After the btrfs ioctl completes this fd is closed, which then puts a reference to that file, leading to a refcount underflow.

Weakness

The product uses, accesses, or otherwise operates on a resource after that resource has been expired, released, or revoked.
