CVE-2008-2372
Publication date 2 July 2008
Last updated 24 July 2024
Ubuntu priority
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
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)
