Description

This security bulletin contains information about 1 security vulnerability.


1) Improper input validation (CVE-ID: CVE-2008-2372)

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The Linux kernel 2.6.24 and 2.6.25 before 2.6.25.9 allows local users to cause a denial of service (memory consumption) via a large number of calls to the get_user_pages function, which lacks a ZERO_PAGE optimization and results in allocation of 'useless newly zeroed pages.'
