Description OSIDB Bzimport 2025-03-06 16:01:15 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ubifs: skip dumping tnc tree when zroot is null

Clearing slab cache will free all znode in memory and make
c->zroot.znode = NULL, then dumping tnc tree will access
c->zroot.znode which cause null pointer dereference.
