Details
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.
