Descriptions

A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only shared memory mappings. This flaw allows an unprivileged, local user to gain write access to read-only memory mappings, increasing their privileges on the system.

Se encontró una condición de carrera en la forma en que el subsistema de memoria del kernel de Linux manejaba la ruptura de copia en escritura (COW) de las asignaciones de memoria compartida privada de sólo lectura. Este fallo permite a un usuario local no privilegiado conseguir acceso de escritura a las asignaciones de memoria de sólo lectura, aumentando sus privilegios en el sistema
