CVE-2011-2496
Published: 06 October 2011
Integer overflow in the vma_to_resize function in mm/mremap.c in the Linux kernel before 2.6.39 allows local users to cause a denial of service (BUG_ON and system crash) via a crafted mremap system call that expands a memory mapping.
From the Ubuntu security team
Robert Swiecki discovered that mapping extensions were incorrectly handled. A local attacker could exploit this to crash the system, leading to a denial of service.
