Comment 6 Alex 2024-06-09 16:19:18 UTC

The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-26962 is: CHECK	Maybe valid. Check manually. with impact LOW (that is an approximation based on flags DEADLOCK INIT DMAorINTERRUPT HARDWARE  ; 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.
