[ubuntu-it] Linux -- Kernel when running on PowerPC

[Patrizio O.C. Melis]

The chrp_show_cpuinfo function (chrp/setup.c) in Linux kernel 2.4.21 through
2.6.18-53, when running on PowerPC, might allow local users to cause a
denial of service (crash) via unknown vectors that cause the of_get_property
function to fail, which triggers a NULL pointer dereference.
