Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy easily misused). strcpy(p[i].device, current.dinfo->devices[i].device_name); data/prometheus-node-exporter-1.0.1+ds/collector/devstat_freebsd.h:43:2: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. char device[DEVSTAT_NAME_LEN]; data/prometheus-node-exporter-1.0.1+ds/collector/devstat_freebsd.h:23:11: [1] (buffer) read: Check buffer boundaries if used in a loop including recursive loops (CWE-120, CWE-20). uint64_t read; data/prometheus-node-exporter-1.0.1+ds/collector/devstat_freebsd.h:30:11: [1] (buffer) read: Check buffer boundaries if used in a loop including recursive loops (CWE-120, CWE-20). uint64_t read; data/prometheus-node-exporter-1.0.1+ds/collector/devstat_freebsd.h:37:10: [1] (buffer) read: Check buffer boundaries if used in a loop including recursive loops (CWE-120, CWE-20). double read; ANALYSIS SUMMARY: Hits = 5 Lines analyzed = 5284 in approximately 0.27 seconds (19847 lines/second) Physical Source Lines of Code (SLOC) = 1377 Hits@level = [0] 0 [1] 3 [2] 1 [3] 0 [4] 1 [5] 0 Hits@level+ = [0+] 5 [1+] 5 [2+] 2 [3+] 1 [4+] 1 [5+] 0 Hits/KSLOC@level+ = [0+] 3.63108 [1+] 3.63108 [2+] 1.45243 [3+] 0.726216 [4+] 0.726216 [5+] 0 Symlinks skipped = 1 (--allowlink overrides but see doc for security issue) Dot directories skipped = 3 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
