Red Hat Product Errata RHSA-2011:0017 0 normal SHIPPED_LIVE Important: Red Hat Enterprise Linux 5.6 kernel security and bug fix update 2011-01-13 10:37:42 UTC

Description Eugene Teo (Security Response) 2010-05-21 08:20:30 UTC 
Description of problem:
There is a typo here.  We should be testing "*dentry" instead of "dentry".  If
"*dentry" is an ERR_PTR, it gets dereferenced in either mkdir() or create()
which would cause an OOPs.

This bug has been in the kernel since 2.6.14-rc2 via b67dbf9d.
