I understand why this occurs. I have reported it before: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=245878 Status: Closed Works As Intended What steps can we take to improve this? vuxml will continue to report all i386 hosts as vuln until the next kernel version bump. Users have no choice but to ignore the reports. Invalid false positives lead to alert fatigue. Is there a way to avoid this situation where properly patched hosts are not incorrectly labelled as vulnerable? -- Dan Langille d...@langille.org _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
