Check manually. with impact MODERATE (that is approximation based on flags LOCK SIMPLEFIX ; these flags parsed automatically based on patche data). Such automatic check happens only for Low/Moderates (and only when not from reporter, but parsing already existing CVE). Highs always checked manually (I check it myself and then we check it again in Remediation team). In rare cases some of the Moderates could be increased to High later. This issue has been addressed in the following products: Red Hat Enterprise Linux 8.8 Extended Update Support Via RHSA-2024:3810 https://access.redhat.com/errata/RHSA-2024:3810 |
