*** This bug is a security vulnerability ***

Public security bug reported:

It was discovered that the proc_ns_follow_link() function did not
properly return the LAST_BIND value in the last pathname component as is
expected for procfs symbolic links, which could lead to excessive
freeing of memory and consequent slab corruption. A local, unprivileged
user could use this flaw to crash the system.
