Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: nfs: corrige la pérdida de memoria acl de posix_acl_create(). Al buscar en otro informe de nfs xfstests, encontré que acl y default_acl en nfs3_proc_create() y las rutas de error de nfs3_proc_mknod() posiblemente se hayan filtrado. Arréglelos con anticipación.
