Description Alex Legler (RETIRED) archtester gentoo-dev Security 2009-08-19 09:20:30 UTC
CVE-2009-2846 (
  The eisa_eeprom_read function in the parisc isa-eeprom component
  (drivers/parisc/eisa_eeprom.c) in the Linux kernel before 2.6.31-rc6
  allows local users to access restricted memory via a negative ppos
  argument, which bypasses a check that assumes that ppos is positive
  and causes an out-of-bounds read in the readb function.

I believe the bug is fixed in the more recently stable kernels.
Comment 2 Guy Martin (RETIRED) gentoo-dev 2010-08-02 18:50:38 UTC
vanilla-sources stable from some time already.

Shall I close ?

The work for hppa is done. CC back if security needs something.
