Summary
  • (es) 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.
