CVE-2011-2479
Published: 6 October 2011
The Linux kernel before 2.6.39 does not properly create transparent huge pages in response to a MAP_PRIVATE mmap system call on /dev/zero, which allows local users to cause a denial of service (system crash) via a crafted application.
From the Ubuntu Security Team
It was discovered that an mmap() call with the MAP_PRIVATE flag on "/dev/zero" was incorrectly handled. A local attacker could exploit this to crash the system, leading to a denial of service.
