In the Linux kernel, the following vulnerability has been resolved: mm: huge_memory: don't force huge page alignment on 32 bit The Linux kernel CVE team has assigned CVE-2024-26621 to this issue. Upstream advisory: https://lore.kernel.org/linux-cve-announce/2024030255-CVE-2024-26621-9300@gregkh/T/#u
Created kernel tracking bugs for this issue: Affects: fedora-all [bug 2267506]
This was fixed for Fedora with the 6.7.6 stable kernel updates.
This does not impact RHEL8 or RHEL9 at this time as we do not have this code in our kernel. The issue was not introduced until v6.7 which we have not pulled into RHEL8 or RHEL9... As an aside, we do have these two patch which introduces the same code- but also removes it at the same time- so we can disregard: eebc80b8a167 Revert "mm: align larger anonymous mappings on THP boundaries" c97e82038959 mm: align larger anonymous mappings on THP boundaries Closing the triaging jiras accordingly...
The result of automatic check (that is developed by Alexander Larkin) for this CVE-2024-26621 is: CHECK Maybe valid. Check manually. with impact LOW (that is an approximation based on flags ; 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.
