CVE-2008-2372

Priority
Low
Description
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."
Ubuntu-Description
It was discovered that the disabling of the ZERO_PAGE optimization could
lead to large memory consumption. A local attacker could exploit this
to allocate all available memory, leading to a denial of service.
