Score breakdown

The Linux kernel from v2.3.36 before v2.6.39 allows local unprivileged users to cause a denial of service (memory consumption) by triggering creation of PTE pages.

From the Ubuntu Security Team

The linux kernel did not properly account for PTE pages when deciding which task to kill in out of memory conditions. A local, unprivileged could exploit this flaw to cause a denial of service.
