Hi Alex, It is not present. The two hits you got from grep just mention it. First is 9c0ebe52fbe56 ("[security] audit: purge audit_log_string from the intra-kernel audit API"), where 59438b46471a is mentioned as missing in a "Conflict" explanation: > Conflicts: > - commit 59438b46471a ("security,lockdown,selinux: implement SELinux lockdown") > from v5.6-rc1, not backported, omos: would break things, class not in policy yet The second is 6b146f48fbdbf ("[security] security: only build lsm_audit if CONFIG_SECURITY=y"). It has 59438b46471a included in "Fixes" tag, but that doesn't mean 59438b46471a is in the tree.
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2021-47128 is: CHECK Maybe valid. Check manually. with impact LOW (that is an approximation based on flags DEADLOCK BPF IMPROVEONLY ; 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.
