NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-bootwrapper package and not the kernel-bootwrapper package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
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.
