  "details": "In the Linux kernel, the following vulnerability has been resolved:  mm/mempolicy: fix memory leaks in weighted_interleave_auto_store()  weighted_interleave_auto_store() fetches old_wi_state inside the if (!input) block only.  This causes two memory leaks:  1. When a user writes \"false\" and the current mode is already manual,    the function returns early without freeing the freshly allocated    new_wi_state.  2. When a user writes \"true\", old_wi_state stays NULL because the    fetch is skipped entirely. The old state is then overwritten by    rcu_assign_pointer() but never freed, since the cleanup path is    gated on old_wi_state being non-NULL. A user can trigger this    repeatedly by writing \"1\" in a loop.  Fix both leaks by moving the old_wi_state fetch before the input check, making it unconditional.  This also allows a unified early return for both \"true\" and \"false\" when the requested mode matches the current mode.  Reviewed by: Donet Tom \u003cdonettom@linux.ibm.com\u003e",
