682641: CVE-2011-1090 kernel: nfs4: Ensure that ACL pages sent over NFS were not allocated from the slab

The MITRE CVE dictionary describes this issue as:

The __nfs4_proc_set_acl function in fs/nfs/nfs4proc.c in the Linux kernel before 2.6.38 stores NFSv4 ACL data in memory that is allocated by kmalloc but not properly freed, which allows local users to cause a denial of service (panic) via a crafted attempt to set an ACL.
