Published: 2025-03-06 | Last Modified: 2026-07-14 | Status: Modified

Description

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.

Additional Descriptions (1)

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ubifs: omite el volcado del árbol tnc cuando zroot es nulo. Limpiar el caché de slab liberará todos los znode en la memoria y hará que c->zroot.znode = NULL, luego, al volcar el árbol tnc se accederá a c->zroot.znode, lo que provocará una desreferencia del puntero nulo.
