The Linux kernel 2.6.9 before 2.6.9-67 in Red Hat Enterprise Linux (RHEL) 4 on Itanium (ia64) does not properly handle page faults during NUMA memory access, which allows local users to cause a denial of service (panic) via invalid arguments to set_mempolicy in an MPOL_BIND operation.
Improper Input Validation The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly.
