  "details": "In the Linux kernel, the following vulnerability has been resolved:  dm-stats: fix a crash if allocation of per-cpu data fails  If \"dm_kvzalloc(percpu_alloc_size, cpu_to_node(cpu))\" fails, the code jumps to the \"out\" label and calls dm_stat_free. dm_stat_free does \"for_each_possible_cpu(cpu) { dm_kvfree(s-\u003estat_percpu[cpu][0].histogram, s-\u003ehistogram_alloc_size);\", which crashes with NULL pointer dereference if s-\u003estat_percpu[cpu] is NULL.  This commit fixes the bug by testing s-\u003estat_percpu[cpu] for NULL before using it.",
