The result of automatic check (that is developed by Alexander Larkin) for this CVE-2021-46993 is: 	SKIP	The Fixes patch not applied yet, so unlikely that actual: 69842cba9ace84849bb9b8edcdf2cefccd97901c	YES			NO	YES	unknown (where first YES/NO value means if related sources built).

Comment 7 Alex 2024-06-09 15:31:00 UTC
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2021-46993 is: CHECK	Maybe valid. Check manually. with impact MODERATE (that is approximation based on flags WRITE OOB 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.
