CVE-2009-2849 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-2849):
  The md driver (drivers/md/md.c) in the Linux kernel before 2.6.30.2
  might allow local users to cause a denial of service (NULL pointer
  dereference) via vectors related to "suspend_* sysfs attributes" and
  the (1) suspend_lo_store or (2) suspend_hi_store functions.  NOTE:
  this is only a vulnerability when sysfs is writable by an attacker.
