Comment 4 Alex 2024-06-09 16:12:14 UTC
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-36929 is: CHECK	Maybe valid. Check manually. with impact MODERATE (that is an approximation based on flags REMOTE DANGER SKB  ; these flags parsed automatically based on patch 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.
