"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: s390: pci: Fix memory accounting for pinned/unpinned pages\n\nThe account_mem() and unaccount_mem() functions call get_uid() which\nincrements the reference count of struct user_struct on every invocation.\nBut we don't decrement the count by calling free_uid(). It also\naccounted/unaccounted the pages against the current->mm. But its possible\nthe unaccount_mem() can be called from a different process context than the\none that originally pinned the pages.\n\nLet's fix this by storing the pinning process user_struct and mm_struct\nwhen accounting for pinned pages, and subsequently free these resources\nwhen the pages are unpinned.\n\n[borntraeger@linux.ibm.com: Fixed whitespace]"
