Upstream advisory: https://lore.kernel.org/linux-cve-announce/2024030413-CVE-2021-47090-a429@gregkh/T
We have the fix for this issue in both RHEL8 and RHEL9: $ kerneloscope downstream 2a57d83c78f8 557359d4abbd (in rhel-8.7, rhel-8.8, rhel-8.9, rhel-8.10) mm/hwpoison: clear MF_COUNT_INCREASED before retrying get_any_page() ce8d02be3349 (in rhel-9.0, rhel-9.1, rhel-9.2, rhel-9.3, rhel-9.4) mm/hwpoison: clear MF_COUNT_INCREASED before retrying get_any_page()
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2021-47090 is: CHECK Maybe valid. Check manually. with impact MODERATE (that is approximation based on flags READ DANGER 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.
