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