Last modified
CVE-2011-2496 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.49% chance of exploitation in the next 30 days.
