When a\nuser provides a param_count close to UINT_MAX via the device mapper\ntable string, this unsigned addition wraps around to a small value,\ncausing the subsequent `argc < *args_used` check to be bypassed.\n\nThe overflowed param_count is then passed as argc to dm_dirty_log_create(),\nwhere it can cause out-of-bounds reads on the argv array.\n\nFix by comparing param_count against argc - 2 before performing the\naddition, following the same pattern used by parse_features() in the\nsame file. Since argc >= 2 is already guaranteed, the subtraction is\nsafe.",
