Descriptions

In the Linux kernel, the following vulnerability has been resolved:

mm, slub: fix potential use-after-free in slab_debugfs_fops

When sysfs_slab_add failed, we shouldn't call debugfs_slab_add() for s
because s will be freed soon. And slab_debugfs_fops will use s later
leading to a use-after-free.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: mm, slub: corrige el posible use-after-free en slab_debugfs_fops Cuando sysfs_slab_add falla, no debemos llamar a debugfs_slab_add() para s porque s se liberará pronto. Y slab_debugfs_fops usará s más tarde, lo que conducirá a un use-after-free.
