+* +LIBFOO_IGNORE_CVES+ is a space-separated list of CVEs that tells
+  Buildroot CVE tracking tools which CVEs should be ignored for this
+  package. This is typically used when the CVE is fixed by a patch in
+  the package, or when the CVE for some reason does not affect the
+  Buildroot package. A Makefile comment must always preceed the

+----------------------
+# 0001-fix-cve-2020-12345.patch
+LIBFOO_IGNORE_CVES += CVE-2020-12345
+# only when built with libbaz, which Buildroot doesn't support
+LIBFOO_IGNORE_CVES += CVE-2020-54321
