CVE-2011-2496

Priority
Description
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.
Ubuntu-Description
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.
