CVE request: Linux kernel: xfs: _xfs_buf_find NULL pointer dereference

[P J P <ppandit () redhat com>]

  Hello,

Linux kernel built with support for XFS file system is vulnerable to a NULL
pointer dereference flaw. This occurs while accessing blocks beyond the end
of the file system, possibly on a corrupted device.

A user able to mount the file system could use this flaw to crash the kernel, 
resulting in DoS.
