Chernikov <melifaro@FreeBSD.org> CommitDate: 2021-05-30 10:30:53 +0000 Fix a use after free in update_rtm_from_rc(). update_rtm_from_rc() calls update_rtm_from_info() internally. The latter one may update provided prtm pointer with a new rtm. Reassign rtm from prtm afeter calling update_rtm_from_info() to avoid touching the freed rtm.
