CVE-2008-2372

Published: 02 July 2008

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."

From the Ubuntu security team

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.

Notes

AuthorNote
kees
is this even security-relevant?
linux-2.6: 89f5b7da2a6bad2e84670422ab8192382a5aeb9f
and also: 672ca28e300c17bf8d792a2a7a8631193e580c74 (vmware breakage)
this is being fixed via -proposed -20 abi (which will likely be -22 in the end)
