CVE-2007-3739

Published: 14 September 2007

mm/mmap.c in the hugetlb kernel, when run on PowerPC systems, does not prevent stack expansion from entering into reserved kernel page memory, which allows local users to cause a denial of service (OOPS) via unspecified vectors.

From the Ubuntu security team

It was discovered that hugetlb kernels on PowerPC systems did not prevent the stack from colliding with reserved kernel memory. Local attackers could exploit this and crash the system, causing a denial of service.
