kernel: nfsd: fix vm overcommit crash

Published Jun 3, 2010

Description

mm/shmem.c in the Linux kernel before 2.6.28-rc3, when strict overcommit is enabled, does not properly handle the export of shmemfs objects by knfsd, which allows attackers to cause a denial of service (NULL pointer dereference and knfsd crash) or possibly have unspecified other impact via unknown vectors.

Affected products

Remediation

Red Hat statement

This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 3, 4 and 5 as they did not include nfs-export support for tmpfs. A future kernel update in Red Hat Enterprise MRG will address this issue.
