CVSS 3.1
5.5 mediumCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2024-26621
Medium (5.5) in linux linux kernel. EPSS 1.0% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
mm: huge_memory: don't force huge page alignment on 32 bit
commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP
boundaries") caused two issues [1] [2] reported on 32 bit system or compat
userspace.
It doesn't make too much sense to force huge page alignment on 32 bit
system due to the constrained virtual address space.
