Descriptions

In the Linux kernel, the following vulnerability has been resolved:

nfs: fix acl memory leak of posix_acl_create()

When looking into another nfs xfstests report, I found acl and
default_acl in nfs3_proc_create() and nfs3_proc_mknod() error
paths are possibly leaked. Fix them in advance.

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.
