Hey Zack- Looks to me we already have the fix for this issue in RHEL 9: $ kerneloscope downstream 0129ab1f268b 0a838c65d871 (in rhel-9.1, rhel-9.2, rhel-9.3, rhel-9.4) kfence: fix memory leak when cat kfence objects I'm going to go ahead and close the jiras for this issue. Let me know if you have any questions.
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2021-47089 is: CHECK Maybe valid. Check manually. with impact LOW (that is an approximation based on flags INIT LEAK ; 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.
