Summary
In the Linux kernel, a vulnerability in the UBIFS filesystem causes a null pointer dereference when dumping the TNC tree after clearing the slab cache. The pointer c->zroot.znode becomes NULL, leading to a system crash.
Risk Assessment
This vulnerability can cause a kernel panic due to null pointer dereference, potentially leading to service disruption and data loss.
Recommendation
Immediately update the Linux kernel to a version containing the fix that adds a null check for c->zroot.znode before dumping the TNC tree.
Original NVD description (English source)
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.
