Описание
The regset (aka register set) feature in the Linux kernel before 3.2.10 does not properly handle the absence of .get and .set methods, which allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a (1) PTRACE_GETREGSET or (2) PTRACE_SETREGSET ptrace call.
Отчет
This issue did not affect the Linux kernel as shipped with Red Hat Enterprise Linux 5 as it did not backport upstream commits 4206d3aa and 5bde4d18.
