"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndm-stats: fix a crash if allocation of per-cpu data fails\n\nIf \"dm_kvzalloc(percpu_alloc_size, cpu_to_node(cpu))\" fails, the code\njumps to the \"out\" label and calls dm_stat_free. dm_stat_free does\n\"for_each_possible_cpu(cpu) { dm_kvfree(s->stat_percpu[cpu][0].histogram,\ns->histogram_alloc_size);\", which crashes with NULL pointer dereference\nif s->stat_percpu[cpu] is NULL.\n\nThis commit fixes the bug by testing s->stat_percpu[cpu] for NULL before\nusing it."
