Red Hat's CVSS score breakdown for CVE-2022-1184 is: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H You're suggesting that Red Hat's rating should have been higher because they didn't factor in low privileges, but that is objectively false because they did score it with low privileges. If they had scored it for high privileges, that would have dropped the rating down from 5.5 to 4.4. There is no reason to believe that CVE-2022-1184 should have been marked as higher impact than it was, and thus I see no reason to justify the likely duplicate CVE-2023-30549 as high. https://access.redhat.com/security/cve/CVE-2022-1184 https://nvd.nist.gov/vuln/detail/CVE-2022-1184 https://nvd.nist.gov/vuln-metrics/cvss/v3-calculator > > > > I am sorry to see that I have already done one step too many according > > > to the incompatible changes policy, and have made the release available > > > to epel-testing.
