Description Bjoern Tropf (RETIRED) gentoo-dev 2009-11-23 17:26:29 UTC 
CVE-2009-3726 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3726):

The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state.
