Looks like we already have this fix in RHEL8 and RHEL9. Closing the triaging jiras accordingly... $ kerneloscope downstream 34796417964b ff6daba7c0d7 (in rhel-8.7, rhel-8.8, rhel-8.9, rhel-8.10) mm/damon/dbgfs: protect targets destructions with kdamond_lock ad2b724628a1 (in rhel-9.1, rhel-9.2, rhel-9.3, rhel-9.4) mm/damon/dbgfs: protect targets destructions with kdamond_lock
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2021-47088 is: CHECK Maybe valid. Check manually. with impact MODERATE (that is approximation based on flags LOCK SIMPLEFIX RACE ; 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.
