Description OSIDB Bzimport 2025-08-16 12:02:43 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net: appletalk: Fix device refcount leak in atrtr_create()

When updating an existing route entry in atrtr_create(), the old device
reference was not being released before assigning the new device,
leading to a device refcount leak. Fix this by calling dev_put() to
release the old device reference before holding the new one.
