CVE-2012-4398

Published: 2 September 2012

The __request_module function in kernel/kmod.c in the Linux kernel before 3.4 does not set a certain killable attribute, which allows local users to cause a denial of service (memory consumption) via a crafted application.

From the Ubuntu security team

Tetsuo Handa reported a flaw in the OOM (out of memory) killer of the Linux kernel. A local unprivileged user can exploit this flaw to cause system unstability and denial of services.

Notes

linux-armadaxp is maintained by OEM

note that patches (1) and (4) are optional but we appear to have the
lot where they are specified

SRU Bug https://bugs.launchpad.net/bugs/1000355 moved from Bugs
