Description:   Opened: 2008-08-15 12:47 0000 
CVE-2008-3534 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-3534):
  The shmem_delete_inode function in mm/shmem.c in the tmpfs implementation in
  the Linux kernel before 2.6.26.1 allows local users to cause a denial of
  service (system crash) via a certain sequence of file create, remove, and
  overwrite operations, as demonstrated by the insserv program, related to
  allocation of "useless pages" and improper maintenance of the i_blocks count.

------- Comment #1 From Robert Buchholz 2008-08-15 12:49:45 0000 ------- 
Fixed in 2.6.25.14 and 2.6.26.1

------- Comment #2 From Kerin Millar 2009-07-20 22:46:49 0000 ------- 
Beware, the patch introduced an independent bug which was subsequently fixed in
2.6.25.17 and 2.6.26.4 respectively:

"fbdefio: add set_page_dirty handler to deferred IO FB"
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=d847471d063663b9f36927d265c66a270c0cfaab

Anyhow, hardened-kernel unaffected at present time. Removing alias.

PS: genpatches-2.6.25-10 added 2.6.25.14. genpatches-2.6.25-3 added 2.6.26.1.
