  "description": "In the Linux kernel, the following vulnerability has been resolved:  KVM: s390: pci: Fix memory accounting for pinned/unpinned pages  The account_mem() and unaccount_mem() functions call get_uid() which increments the reference count of struct user_struct on every invocation. But we don\u0027t decrement the count by calling free_uid(). It also accounted/unaccounted the pages against the current-\u003Emm. But its possible the unaccount_mem() can be called from a different process context than the one that originally pinned the pages.  Let\u0027s fix this by storing the pinning process user_struct and mm_struct when accounting for pinned pages, and subsequently free these resources when the pages are unpinned.
