  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nmm/list_lru: drain before clearing xarray entry on reparent\n\nmemcg_reparent_list_lrus() clears the dying memcg\u0027s xarray entry with\nxas_store(\u0026xas, NULL) before reparenting its per-node lists into the\nparent.  This opens a window where a concurrent list_lru_del() arriving\nfor the dying memcg sees xa_load() == NULL, walks to the parent in\nlock_list_lru_of_memcg(), takes the parent\u0027s per-node lock, and calls\nlist_del_init() on an item still physically linked on the dying memcg\u0027s\nlist.\n\nIf another in-flight thread holds the dying memcg\u0027s per-node lock at the\nsame moment (another list_lru_del, or a list_lru_walk_one running an\nisolate callback), both threads modify -\u003enext/-\u003eprev pointers on the same\nphysical list under different locks.  Adjacent items can corrupt each\nother\u0027s links.\n\nFix it by reversing the order: reparent each per-node list and mark the\nchild\u0027s list lru dead and then clear the xarray entry.  Any concurrent\nlist_lru op that finds the still-set xarray entry either takes the dying\nmemcg\u0027s per-node lock (synchronizing with the drain) or sees LONG_MIN and\nwalks to the parent, where the items now live.",
