GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

GSD-2024-26621

Vulnerability from gsd - Updated: 2024-02-20 06:02
Details
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.
