fs/nfs/nfs4proc.c in the NFS client in the Linux kernel before 4.2.2 does not properly initialize memory for migration recovery operations, which allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) via crafted network traffic.

CVE-2015-8746 [HIGH] CWE-665 kernel: when NFSv4 migration is executed, kernel oops occurs at NFS client
kernel: when NFSv4 migration is executed, kernel oops occurs at NFS client
fs/nfs/nfs4proc.c in the NFS client in the Linux kernel before 4.2.2 does not properly initialize memory for migration recovery operations, which allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) via crafted network traffic.
A NULL pointer dereference flaw was found in the Linux kernel: the NFSv4.2 migration code improperly initialized the kernel structure. A local, authenticated user could use this flaw to cause a panic of the NFS client (denial of service).
Statement: This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, 6 as the code with the flaw is not present in the products listed.
