In the Linux kernel, the following vulnerability has been resolved:
mm/mempolicy: fix memory leak in set_mempolicy_home_node system call
When encountering any vma in the range with policy other than MPOL_BIND or
MPOL_PREFERRED_MANY, an error is returned without issuing a mpol_put on
the policy just allocated with mpol_dup().
This allows arbitrary users to leak kernel memory.
