CWE-476

Description

A flaw was found in the Linux kernel's NFS implementation, all versions 3.x and all versions 4.x up to 4.20. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence. This can panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will be lost.

Affected configurations

• linux linux kernel (>= 3.0 <= 4.20) • redhat developer tools 1.0 • redhat mrg realtime 2.0 • redhat enterprise linux 7.0 • redhat enterprise linux desktop 7.0 • redhat enterprise linux eus 7.4 • redhat enterprise linux server 7.0 • redhat enterprise linux server aus 7.4 • redhat enterprise linux server aus 7.6 • redhat enterprise linux server eus 7.6 • redhat enterprise linux server tus 7.4 • redhat enterprise linux server tus 7.6 • redhat enterprise linux workstation 7.0 • netapp cloud backup • netapp h410c firmware • netapp h300s firmware • netapp h500s firmware • netapp h700s firmware • netapp h300e firmware • netapp h500e firmware • netapp h700e firmware • netapp h410s firmware
