Descriptions
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.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: mm: huge_memory: no forzar una alineación de página enorme en el commit de 32 bits efa7df3e3bb5 ("mm: alinear asignaciones anónimas más grandes en los límites de THP") causó dos problemas [1] [2] informado en un sistema de 32 bits o espacio de usuario compatible. No tiene mucho sentido forzar una gran alineación de páginas en un sistema de 32 bits debido al espacio limitado de direcciones virtuales.
